The functions q and r are defined as follows g(x) = -2x-2
r(x) = x² – 2
Find the value of r(q(4)).
r(9 (4)) =

98

Step-by-step explanation:

So we have the two functions:

And we want to find the value of r(g(4)).

To do so, first find the value of g(4):

Multiply:

Subtract:

Now, substitute this into r(g(4)):

And substitute this value into r(x):

Square:

Subtract:

Therefore:

c. 4 and 1/2 pounds is the answer! : )

the answer to this is a. a^2 + b^2 = c^2
