Over what interval is f(x) negative? Justify your answer.

Answer in interval notation is  (-3, 1)

This is the same as saying -3 < x < 1

=====================================================

Explanation:

Since y = f(x), this means we're looking for points on the red curve such that they have a negative y coordinate. Visually, we're looking for points that are below the horizontal x axis.

These points are shown in the diagram below. I've marked the section we're after in blue. This blue section spans from x = -3 to x = 1. We exclude both endpoints because each x value leads to f(x) = 0, but we want f(x) values smaller than zero.

Please help don’t know answer

consider the expression 7 - 4y. Why would the co-efficient be -4 and not 4?

PLEASE HELP if 5 more than 3 times a number is -4, what is the number?

work out the equation of the line which has a gradient of 2 and passes through the point (1,4)


please answer quick

i will mark you brainiest

When I multiply a - and +, the answer will be a?

Which equation represents the line that passes through
the points (2, 3) and (4, 7)?

1. If you have a McDonalds order where the subtotal comes to
$29.46 and you give a 15% discount coupon, how much will the
new subtotal be?

(Please help) Based on the equation you wrote in part 1, complete the table below (equation is f = 1000t)

When 8 is added to a certain number and the
sum is multiplied by 3, the result is 57.
Find the number.​

Help please with this problem!

can I get people that are actually willing to try instead of stealing points jeez.

What is the difference of the rational expressions below? 3x/x+1 minus 5/x

Which equation represents a line which is parallel to the line 7x - y = 4?

the figure below is made of two triangular prisms. what is the volume of the figure

can someone please help me with this equation? i'll give you the brainliest answer :)​

Sample Response: To find the image after a reflection over the x-axis, I would negate the y-coordinate. To find the image after a reflection over the y-axis, I would negate the x-coordinate. So, reflecting the point (5, 2) over the x- and y-axis, I would get (–5, –2).

Which did you include in your response? Check all that apply.
Negate the y-coordinate.
Negate the x-coordinate.
Get the point (–5, –2).

Given the equation 2x + 4 = 4x - 2, select the reasoning that correctly solves for x.

1) Add 2, subtract 2x, then divide by 2.

2) Add 2, subtract 4x, then divide by -2.

3) Subtract 4, subtract 2x, then divide by-2.

04) Subtract 4, subtract 4x, then divide by 2.

There are five 6-inch sticks and five 10-inch sticks. These sticks can be attached end-to-end to make longer sticks. For example, you can take two 6-inch sticks and one 10-inch stick to make a 22-inch stick (6 + 6 + 10 = 22).How many different lengths of stick can be made out of at least one of the sticks?

Find the number for x. (Divide)

The length of a rectangle is shown below: On a coordinate grid from negative 6 to positive 6 on the x-axis and on the y-axis, two points A and B are shown. The point A is on ordered pair 1, 2, and the point B is on ordered pair negative 3, 2. A straight line joins the points A and B. If the area of the rectangle to be drawn is 12 square units, where should points C and D be located, if they lie vertically below the line that connects B and A, to make this rectangle?
