Question

f(x)=-3x+2

a) express the slope of the secant line of each function in terms of x and h.
b) find msecant for h=.5, .1, and.01 at x=1.
c) find the equation for the secant line at x=1 with h=1.01

I got -3 for a but don't know how to do the others becaus a does not have x or h in it

thanks:)

Answer 1

3x+2 is just a straight line. Makes no sense to talk about secants unless there's more to the problem. Any "secant" line between two points on the graph is just a piece of the graph, with m=-3.

Answer 2

so those cannot be answered???
