Given the function;

[tex]f(x)=x^2-1[/tex]

At x = 1;

[tex]f(1)=1^2-1=0[/tex]

and at x = 7;

[tex]f(7)=7^2-1=49-1=48[/tex]

The rate of change of the function is;

[tex]\begin{gathered} =\frac{48-0}{7-1} \\ =\frac{48}{6} \\ =8 \end{gathered}[/tex]

CORRECT ANSWER: FALSE because the rate of change is NOT 7.
