Question

Given: r(x) = x3 - 7, k(x) = 5 ln (2x) Find: (k ○ r) (x)

Answer 1

The value of (k ○ r) (x) from the given parameters in the task content is; 5 ln(2x³ -14)

What is (k ○ r) (x) from the task content?

If follows from the task content that;

• r(x) = x³ - 7 and k(x) = 5 ln (2x)

It therefore follows that;

(k ○ r) (x) = k(r(x)) = 5 ln (2(x³-7)).

On this note, the expression which represents (k ○ r) (x) is; 5 ln(2x³ -14).
