Homework Statement
Find the slope of the line that joins P (0,2) and Q (x, 2^x+1) for x ≠0. type the expression using x as a variable.
Homework Equations
Rise over Run?
The Attempt at a Solution
I have a picture of the graph but i don't really know what to do, Please help.
I graphed it at x= -3, -2 and -1 cause that was part 1
Okay so i just had a thought in my mind. So we can use limits to find the slope of the secant line, So would i use The limit of 2^x+1 as x approaches 0. But then the slope would be 1, And how would i write the expression in terms of x.
So for when x=-1 the rise/run is .5/1
x=-2 rise over run is .75/2
and when x=-3 rise over run is .875/3
but now how would i do the expression part?
