Question

The graph of which function does not have a y-intercept of (0, 1)?
A. y = -2^x
B. y = 2^-x
C. y =0.1^x
D. y =0.5^x

Answer 1

when x = 0 y = 1
put x = 0 in each equation which option does not give a value of 1?

Answer 2

well these are the answer choices
A.
(0, 1)
B.
(1, 0)
C.
(1, 1)
D.
(0, 0)

Answer 3

now I am confused.
which graph does not have a y-intercept of (0, 1)? it would be graph A .when x = 0 then y is not equal to 1. why do you have these as the answer choices?

Answer 4

My mistake the correct answer choices are A. y=-2^x B. y=2^-x C. y=0.1^x D. y=0.5^x

Answer 5
