Question

Help
Given h(x) = 2x – 1, find h(-1).
Answer:

Answer 1

substitute -1 in for x:

2(-1)-1

-2-1 = -3

final answer: h(-1)=-3

Answer 2

-3

Explanation:

What this tells you is that where you see an x on the right hand side of the equation, you put -1.

h(-1) = 2(-1) - 1

h(-1) = -2 - 1

h(-1) = - 3
