We are given f(x) = 4x and f(x)- 8.x. Exercise (a) Find the instantaneous rate of change of fx) atx=3. Step 1 We are told that for f(x) = 4x², (x)= x. We want to find the instantaneous rate of change of f(x) atx=3. The instantaneous rate of change of fix) is given by f(x). Thus, at x3, the instantaneous rate of change of f(x) is given by the following. (0 )-(C

Find the slope of the tangent to the graph of y f(x) at x = 3. Step 1 We are told that for f(x) = 4x, f(x)= x. We want to find the slope of the tangent to the graph of y=fa) at x 3. The slope of the tangent to the graph of y = f(x) is given by f(x). Thus, at x = 3, the slope of the tangent to the graph of y=f(x) is given by the following. ])=([

Find the point on the graph of y=f(x) atx= 3. Step 1 We are told that for f(x) = 4x², F(x)= x. We want to find the point on the graph of y=f(x) at x-3. The y-value on the graph at x = 3 is given by the following. yw The point on the graph is (x, y) =
