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:

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
