## anonymous one year ago HELP MEDAL AN FAN ! FAST The graph of f(x) = 2x + 1 is shown below. Explain how to find the average rate of change between x = 1 and x = 3.

do you have graph ?

3. Nnesha

if no then plug in 1 and then 3 to find y [f(x) is same as y] then use slope formula to find average rate of change $\huge\rm \frac{ y_2-y_1 }{ x_2-x_1 }$
