The answer is If you would like to find the expression that is equivalent to (t*s) (x), you can calculate this using the following steps:

s (x) = x - 7

t (x) = 4x^2 - x + 3

(t*s) (x) = t (s (x)) = t (x - 7) = 4 (x - 7) ^2 - (x - 7) + 3 = 4 (x - 7) ^2 - x + 7 + 3

The correct result would be 4 (x - 7) 2 - (x - 7) + 3.
