When asking for they are basically asking you to evaluate the function
for -2, find a y value, and plug in that value as x in
Let's do it step-by-step:
1. Find the value of g(-2).
G(x) is given as a graph, therefore, you will have to see what value of axis y marks the graphic when you make x=-2. <em>Check the attached image</em>. As you may notice, the value that function g(x) generates for x= -2 is y= -3. Hence, g(-2)= -3.
2. Substitute the value into f(x).
F(x) is a piecewise function, so we'll need to determine the group the value fits into and calculate with the expession that corresponds for that value. Our value is -3, this value is less than -2, therefore, the function we'll have to use is .
3. Determine the value of f(-3).
Since f(x)= 7 for our value (-3), the result is 7.
4. Express your answer.

Answer:
Step-by-step explanation:
First, we can factor all of the following equations to turn that weird, huge looking thing into ÷
×
. We know that division is simply multiplication by the reciprocal, so that whole equation will turn into
×
×
. Now we can cancel out some values if they are both in the numerator and denominator, which will turn that still huge looking thing into
which is our final answer, as it cannot be simplified further.
Hope this helped! :)
