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) $f(g(x))$

$$e=mc^2$$
