Divide 42 by 4 for one fourth. Divide 13.5 by 5 and multiply that by 2.
Average rate of change: r=[f(b)-f(a)]/(b-a)
r=-60→[f(b)-f(a)]/(b-a)=-60
b=5; f(b)=-213; a=1; f(a)=27
(-213-27)/(5-1)=(-240)/4=-60
Answer: The <span>two points in the table which create an interval with an average rate of change of -60 are:
x f(x)
1 27
5 -213</span>
The type of discount you can get at the store stated in the situation would be a price discount. This is because regardless of the what item you buy in the store or whatever age you have, the discount is applicable with all. Also, this situation might be one that's usually in a surplus or when you want everything to be sold.
