Question

Consider the function f(x)=8-3x^2 find the value of f(x) when x= 3

Answer 1

You start with f(x)=8-3(3)². Then, going in order of PEMDAS, you start with your exponent. So you have f(x)=8-3(9). Then multiplication, f(x)=8-27. Then your subtraction. f(x)=-19

Answer 2

F(3)=8-3(3)^2= -19.....
