Question

Evaluate the function f(x) =-x/2 -7x -2 find f(-9)

Answer 1

Answer:

$f(-9)=\frac{131}{2}$

Step-by-step explanation:

In order to evaluate a function at a given x-value, plug in that value into the actual function

$f(x)=-\frac{x}{2} -7x-2\\\\f(-9)=-\frac{9}{2} -7(-9)-2\\\\f(-9) = \frac{131}{2}$
