Question

Consider the following functions. Find five ordered pairs that satisfy the function, g(x)=x^2-5

Answer 1

Evaluate for different values of x:

$\begin{gathered} x=0 \\ g(0)=0^2-5=-5 \\ ------------- \\ x=1 \\ g(1)=1^2-5=-4 \\ ------------- \\ x=2 \\ g(2)=2^2-5=-1 \\ ------------- \\ x=3 \\ g(3)=3^2-5=4 \\ ------------- \\ x=4 \\ g(4)=4^2-5=11 \end{gathered}$

Therefore:

$\mleft\lbrace(0,-5\mright),(1,-4),(2,-1),(3,4),(4,11)\}$
