Answer:
Step-by-step explanation:
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)

Answer:
30 degrees
Step-by-step explanation:
<ACB is a central angle while <ADB is an inscribed angle.
Central angles are twice the size of inscribed angles.
Therefore, <ADB*2 = <ACB . 15*2=30
