Answer:
The expression is equivalent to [g o f](2) and the value of [g o f](2) is 125.
Step-by-step explanation:
The given function are
We have to find the value of [g o f](2).
(f\circ g)(x)=f(g(x))
[tex[\because f(x)=7x^2-3][/tex]
[tex[\because g(x)=5x][/tex]
Therefore the expression is equivalent to [g o f](2) and the value of [g o f](2) is 125.
