Answer
(g o h) (0) = 6
Explanation
g(x) = 3x
h(x) = x² + 2
We are then told to find (g o h) (0)
Normally, (g o h) (x) means writing g(x), but instead of x, we substitute h(x). That is,
(g o h) (x) = g[h(x)]
g(x) = 3x
h(x) = x² + 2
(g o h) (x) = g[h(x)]
= 3[h(x)]
= 3(x² + 2)
= 3x² + 6
(g o h) (0) means when x = 0
(g o h) (x) = 3x² + 6
(g o h) (0) = 3(0)² + 6
= 0 + 6
= 6
Hope this Helps!!!
