Question

Let f(x)=(3x)2 and g(x)=9x2
Find f (1) and g (1)
b) Find f (-4) and g (-4)
c) Are f and g equivalent functions? Why or why not?
d) Let f(s) =s+6 and g (t) =t+6. Are f and g equivalent functions? Why or why not?

Answer 1

The value of the functions will be:

a. f(1) = 3

g(1) = 9

b. f(-4) = 48

g(-4) = 144

c. It should be noted that f and g are not equivalent.

d. f(s) =s+6 and g (t) =t+6 are equivalent functions.

How to illustrate the function?

f(x) = 3x²

g(x) = 9x²

f(1) = 3(1)² = 3

g(1) = 9x² = 9

b. f(-4) = 3(-4)² = 48

g(-4) = 9(-4)² = 144

c. It should be noted that f and g are not equivalent.

d. When f(s) =s+6 and g (t) =t+6 f and g equivalent functions because a variable was given.
