Given the function f(x)-3x^2+4x+6, find f(2) and f(3). Choose the statement that is true concerning these two values

Answer 1

f(2)=2, f(3)=-9, so the value of f(2) is larger than the value of f(3)

Explanation:

To find the value of f(2) we first need to substitute 2 for all the x-values in the equation.

`f(2)=-3(2)^(2) +4(x)+6`

From there we can simply do the math, using the PEMDAS method:

`f(2)=-3(2)^(2) +4(2)+6\\f(2)=-3(4)+8+6\\f(2)=-12+8+6\\f(2)=2`

To find the value of f(3), we do the same.

`f(3)=-3(3)^(2)+4(3)+6\\ f(3)=-3(9)+12+6\\f(3)=-27+12+6\\f(3)=-9`
