the function ( y = f(x) ) is graphed below. what is the average rate of change of the function ( f(x) ) on the interval ( 1 leq x leq 2 )?
Answer
Explanation:
Step1: Recall the formula for average rate of change
The average rate of change of a function (y = f(x)) on the interval ([a,b]) is (\frac{f(b)-f(a)}{b - a}). Here, (a = 1) and (b=2).
Step2: Find (f(1)) and (f(2)) from the graph
From the graph, when (x = 1), (y=f(1)=5) (since the point ((1,5)) lies on the graph of (y = f(x))), and when (x = 2), (y = f(2)=7) (since the point ((2,7)) lies on the graph of (y = f(x))).
Step3: Substitute values into the formula
Substitute (a = 1), (b = 2), (f(1)=5), and (f(2)=7) into the formula (\frac{f(b)-f(a)}{b - a}). We get (\frac{f(2)-f(1)}{2 - 1}=\frac{7 - 5}{2-1}).
Step4: Simplify the expression
(\frac{7 - 5}{2-1}=\frac{2}{1}=2).
