Question

F(x)=-4x^2-x-3 Find f(1)

Answer 1

f(1)=-8

Explanation:

Value of a function

Given a function expressed as y=f(x), where x is the independent variable, and y is the dependent variable, we can give x any desired value in the domain of f.

We are given the function

`f(x)=-4x^2-x-3`

To find f(1), we replace the variable x for the value 1, and we get:

`f(1)=-4(1)^2-(1)-3`

`f(1)=-4*1-1-3`

`f(1)=-4-1-3=-8`

Thus, f(1)=-8
