Question

Use the following graph to estimate the rate of change of the function at x=0.6 using the points (0,0) and (1,−0.5)

Answer 1

So we have points (0,0) and (1,-0.5)
a+b=-0.5 then, 1+b=-0.5 which equals to 0. So the equations becomes f(x)=\[x^{3}\] - 1=-1.5
At x we now have x=0.6
f(0.6)=3 x(0.6)\[^{2}\] -3 x(0.6)
The rate of change is x=0.6 and -7.2

Hope this helps!

Answer 2

The equation I typed in got a bit mixed up but i hope you understand it
