Question

if $h(x) = x^2 - 5x + 7$, find each value.

1. $h(2)$
2. $h(-5)$

Explanation:

Step1: Substitute $x=2$ into $h(x)$

$h(2) = (2)^2 - 5(2) + 7$

Step2: Calculate each term

$h(2) = 4 - 10 + 7$

Step3: Simplify to find $h(2)$

$h(2) = 1$

Step4: Substitute $x=-5$ into $h(x)$

$h(-5) = (-5)^2 - 5(-5) + 7$

Step5: Calculate each term

$h(-5) = 25 + 25 + 7$

Step6: Simplify to find $h(-5)$

$h(-5) = 57$

Answer:

$h(2)=1$
$h(-5)=57$
