F(-5)-f(-2)/-5-(-2)
=-644-(-26)
=-618/-3
=206
The answer is A.
Find the average rate of change for the function between the given values.
f(x)=6x^3+4x^2+6; from -5 to -2
Answer: f(x+h)-f(x)/h=3x^2+3xh+8x+4h
I plugged in -2 for x and -3 for h and my result was 11.
Don't know if I am doing this right. Please help.
