Question

Find the x-intercept of the exponential function y = ax - b, where b > 0.
A)(log a - log b, 0)
B)(log b - log a, 0)
C)(log b/log a, 0)
D)(log a/log b, 0)

Answer 1

help asap please

Answer 2

is this the equation? \[y = a^x - b\]

Answer 3

yes

Answer 4

at the x intercept y = 0 so the equation becomes \[0 = a^x-b\]

Answer 5

next we need to solve for x, any ideas?

Answer 6

im am just absolutely lost on this question

Answer 7

first of all you want to isolate a^x so that you can use log to bring the x down

Answer 8

so add b to both sides

Answer 9

can you do that?
