Question

The function h(x) has y-intercept 3 and goes through the point (a,a+3). what is the formula?

Answer 1

well all you need to do is find the slope as you know 2 points, one of which is an intercept

the points are (0,3) and (a, a + 3)

so the slope is

m = (a + 3 - 3)/(a - 0)

then you can substitute into the equation

y = mx + b where m = slope of the line and b is the y-intercept

Answer 2

But this is an exponential problem

Answer 3

where does it say its an exponential equation... ?

Answer 4

ok... so the then for the exponential equation when x = 0 y = 3 as the intercept

so the form is y = 3e^kx
