Which function represents the graph of y=4^x −1 ? q r s t

y=4^x −1

x intercept is the point when y = 0, so you sub in 0 for y:

0 = 4^x - 1

4^x = 1

Any number excluding 0 that is raised to the the exponent 0 always equals 1, 0^0 is undetermined.

x = 0

x intercept = (0,0)

If the x intercept is at the origin (0,0) than the y intercept is also (0,0)

s is the only line that passes through (0,0)

s is the correct answer

Step-by-step explanation: i took the test (:

P'(head)=65/100

Step-by-step explanation:

Total flip=100 times

Land on heads=65 times

65 over 100.
