Question

I need help please!!!!!

Answer 1

y-intercept is (0, -2) and asymptote of y = -2.5

Explanation:

If you substitute 0 in for x and simplify, then you will have the y-intercept

y =
`(1)/(2) (7)^(0) - 2.5 = (1)/(2) (1) - 2.5 = (1)/(2) - 2.5 = -2`

The y-intercept is (0, -2)

If the -2.5 were not there, then the graph would have an asymptote at y = 0 or the x-axis

The -2.5 moves the graph down 2.5 units so that y = -2.5 is the asymptote

Therefore, the first answer is correct
