Need with these 3 math questions on functions .

Q4.

all real numbers greater than or equal to 0.

Q.

The range is read from the y axis. Therefore the range = (-∞ , 1]

{y | y ≤ 0}

Q.

The first part of the graph has a slope = 2, therefore it's y = 2x.

The second part of the graph is horizontal line y= 4.

Therefore your answer is:

according to egenuity the answer is

step-by-step explanation:

d. 344.22

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
