Question

If h(x) = x2-5x + 7
find: h(-5)

Answer 1

It is −3)=57. Explanation: Hence h(x)=5x2−4x then just replace x for −3. h(−3)=5⋅(−3)2−4⋅(−3)⇒h(−3)=45+12⇒h(−3)=57

Answer 2

h(-5)=22

Explanation:

Replace x with -5.

`h(-5) = (-5)2-5(-5) + 7`

Simplify.

`h(-5)=-10+25+7`

Simplify.

`h(-5)=22`
