given function f(X)=X^3+3x
findthe rate of change between the two stated values for x:1 to 2
find the equation of a secant line (1,f(1)and(2,f(2))
college algebra -
f(1) = 4
f(2) = 14
rate of change = slope = 10
line containing (1,4) with slope 10 is
(y-4) = 10(x-1)
Note to zachary - college algebra -
