Verified
Answer

The value of the g(3) is 3.

1Step-1 – Functional notation

The Function notation is a way to write functions that is easy to read and understand.

2Step-2 – Substitute the value of x .

If g(x)=-4x3+7, then g(3) represents that we need to substitute 3 in place of x.

g(3)=-4(3)3+7

3Step-3 – Simplify the equation.

 g(3)=123+7g(3)=4+7g(3)=3

So, the value of g(3) is 3.
