(x,y) (2,15) (7,30)
Rate of change is finding slope.
(30-15)/(7-2)=
15/5=
3

Answer:

3

Step-by-step explanation:

Given :

x     f(x)

-2      0

2      15

7       30

Solution :

Since the average rate of change is slope

So,

Slope m = [tex]\frac{f(x_{2} )-f(x_{1}) }{x_{2}-x_{1} }[/tex]

So, take [tex]f(x_{2} )=30,f(x_{1})=15,x_{2}=7,x_{1} =2[/tex]

Thus the slope = [tex]\frac{30-15 }{7-2} [/tex]

[tex]\frac{15}{5}}[/tex]

[tex]3[/tex]

Thus the average rate of change for the given function is 3
