# Function Notation [ $f(x), g(x)$ ] (Functions)

1. 1
Given $f(x)=2x^2-3x+4$, determine the value of:

a) $f(-2)$

b) $f(x-2)$

Good test question !
2. 2
Given $f(x)=x^2-2x+5$, determine the value of:

a) $f(-3)$

b) $f(x-3)$
3. 3
Given $f(x)=x^2+3$, determine the value of:

a) $f(3x)$

b) $f(\frac{1}{x})$
4. 4
Given $f(x)=\frac{x+2}{x-2}$, determine the value of:

a) $f(3a)$

b) $f(\frac{1}{x})$

Part b) is a tough question !
5. 5
Given $f(x)=x^2-4x$ and $g(x)=x-3$, determine the value of:

a) $f(2)$

b) $g(3)$

c) $f(g(1))$

d) $f(g(x))$
6. 6
Given $f(x)=2x^2-4x+3$ and $g(x)=x-2$, determine the value of:

a) $2f(-2)-3g(4)$

b) $f(g(-1))$

c) $f(g(x))$

$$e=mc^2$$
