If s (x) = x-7 and f (x) = 4x? - X+3, which expression is equivalent to (tos) (x) ?

04 (x-7) 2 - X-7 + 3

0 4 (x-7) 2 - (x-7) + 3

(4x2 - x + 3) - 7

0 (4x2 - x+3) (x-7)

4 (x-7) ^2 - (x-7) + 3 (Assuming t is f)

Step-by-step explanation:

Let s (x) = x-7 and t (x) = 4x^2-x+3.

(t o s) (x) = t (s (x)) = t (x-7)

Before I continue this means replace the orginal x in t with x-7.

This will then give you

4 (x-7) ^2 - (x-7) + 3
