The value of the composite function is g(h(f(-1)))=80

Step-by-step explanation:

In this problem we have the following functions:

f(x)=x^2+2\\g(x)=x^2-1\\h(x)=3x

We want to find the composite function

g(h(f(x)) and compute its value in x = -1.

In order to do that, we start by calculating the value of f(x) for x = -1:

f(-1)=(-1)^2+2=1+2=3

Now we compute h(f(x)) for x = -1:

h(f(-1))=3(f(-1))=3(3)=9

And now we compute g(h(f(x))) for x = -1:

g(h(f(-1)))= (h(f(-1))^2-1=9^2-1=80

Find the terminal point p(x y) on the unit circle determined by the given value of t. t = -3 pi / 2
Vlada [557]
-3pi/2 is the same thing as pi/2

the terminal point on the unit circle for pi/2 is (0,1)

so that means the terminal point for -3pi/2 is also (0,1).
