Question

Find (g of (26) when f(x) = X-2 and g(x) = 7x + 2.
A) "
B) 54
C) 44
D) 1104

Answer 1

To find g(26) when g(x) = 7x + 2, we simply need to substitute x = 26 into the expression for g(x):

g(26) = 7(26) + 2

g(26) = 184

Now, to find (g of f)(x), we need to substitute f(x) into the expression for g(x):

(g of f)(x) = g(f(x)) = 7(f(x)) + 2

Since f(x) = x - 2, we can substitute x - 2 for f(x) in the expression for g(x):

(g of f)(x) = g(x - 2) = 7(x - 2) + 2

Simplifying this expression, we get:

(g of f)(x) = 7x - 12

Now, to find (g of f)(26), we simply substitute x = 26 into the expression we just found:

(g of f)(26) = 7(26) - 12

(g of f)(26) = 182

Therefore, the answer is A) (not listed).
