The rate of change of function is: 4
Further explanation:
The formula for calculating rate of change of function is:
[tex]Rate\ of\ change = \frac{f(b)-f(a)}{b-a}[/tex]
Here,
a = 1 and b = 3
So,
[tex]f(1) = (1)^2-3\\= 1-3\\=-2\\f(3) = (3)^2-3\\=9-3\\=6[/tex]
Putting the values
[tex]Rate\ of\ change= \frac{f(3)-f(1)}{3-1} \\= \frac{6-(-2)}{2} \\= \frac{6+2}{2} \\= \frac{8}{2}=4[/tex]
The rate of change of function is: 4
