Question

F(x)=2x+3 g(x)=x^2
solve the equation g.f(x)=100

Answer 1

Answer: = 16

Explanation:

The value of f(4) can be found by replacing x with 4 in the equation f(x) = 2x + 3. So, f(4) = 2(4) + 3 = 11.

The value of g(4) can be found by replacing x with 4 in the equation g(x) = x^2. So, g(4) = 4^2 = 16.
