Question

if $f(x)=x^2$, $g(x)=5x$, and $h(x)=x+4$, find each value.
enter a number.
$f(-3)=$
$g(-2)=$
$h(-7)=$

Explanation:

Step1: Substitute $x=-3$ into $f(x)$

$f(-3) = (-3)^2$

Step2: Calculate the square

$f(-3) = 9$

Step3: Substitute $x=-2$ into $g(x)$

$g(-2) = 5\times(-2)$

Step4: Perform the multiplication

$g(-2) = -10$

Step5: Substitute $x=-7$ into $h(x)$

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

Step6: Perform the addition

$h(-7) = -3$

Answer:

$f(-3)=9$
$g(-2)=-10$
$h(-7)=-3$
