nope it just gives me the problem: f(x)=3x^2+4x-2

\[3x ^{2}+4x-2 = (x+ \frac{2}{3})^{2}-\frac{10}{9}\]

Ok you just have to plug in whatever value you get in place of x,for example lets suppose we had to find f(-3)
So,
f(x)=3x^2+4x-2
f(x)=3(-3)^2+4(-3)-2
f(x)=27-12-2
f(x)=13

@hba this is the graph of that function so we can see f of each given value of x
