Question

Evaluate p(x)=−3+4x when x=−2,0, and 5 .

Answer 1

when x=-2, -3-8=-11

When x=0, -3+0=-3

When x=5, -3+20=17

Answer 2

When x = -2
p(-2) = -3 + 4(-2)
p(-2) = -3 + -8
Answer: p(-2) = -11

When x = 0
p(0) = -3 + 4(0)
p(0) = -3 + 0
Answer: p(0) = -3

When x = 5
p(5) = -3 + 4(5)
p(5) = -3 + 20
Answer: p(5) = 17
