Evaluate the function rule for the given value.
y = 15 • 3x for x = –3
Is the answer -135?

Answer 1

Answer: Yes

Explanation:

Hi, to answer this question we have to substitute x =-3 on the function given, and solve for the variable y.

y = 15 • 3x

Replacing the value of the variable x by -3:

y = 15 • 3(-3)

Multiplying

y = 15 .-9

y = -135

It is correct, the answer is y= -135

Feel free to ask for more if needed or if you did not understand something.

Answer 2

Y = 15 • 3x
Y = 15 • 3(-3)
Y = 15 • (-9)
Y = -135
