Given :-

  • f(x) = -9x + 7 .

To Find :-

  • The value of f(3) .

Solution :-

The given function is ,

→ f(x) = -9x + 7 .

And we need to find out its value at x = 3 , that is f(3) . So just substitute x = 3 ,

→ f(3) = -9*3 +7

→ f(3) = -27+7

→ f(3) = -20

Hence the required answer is-20 .

I hope this helps.
