Question

Evaluate f(x)=−3x+15 when x=−4, x=0, and x=5.

Answer 1

Answer:

27, 15, 0

Step-by-step explanation:

Here f(x)= -3x+15

First, putting x= -4

then, f(-4)= -3× (-4)+15

= 12+15

= 27

Now, putting x=0

then, f(0)= -3×(0)+15

= 0+15

= 15

Now, putting x=5

then, f(5)= -3×(5)+15

= -15+15

= 0
