Given f(x) = 9x - 5 and g(x) = x^2 choose the expression for (f g) (x)

Step-by-step explanation:

Given: and .

We are asked to find

This is composition of two functions. means becomes the input for .

So, now

9x²-5

Step-by-step explanation:

Given f(x) = 9x - 5 and g(x) = x², (f g)x means we will have to substitute g(x) value into f(x).

Since f(x) = 9x-5

(f g)x = 9x²-5

Note that g(x) which is equal to x² will be substituted for value of x in the function of x i.e f(x) making 9x²-5 the required answer.

the first one, all those points on the line just make a strait line.
