Question

Hello can you please help me posted picture of question

Answer 1

For this case we have the following function:
 f (x) = a (b) ^ x
 To find the intersection with the axis, we must evaluate the function for x = 0.
 We have then:
 f (0) = a (b) ^ 0
 f (0) = a (1)
 f (0) = a
 Then, the ordered pair is:
 (0, a)
 Answer:
 (0, a)
 option A

Answer 2

Any variable raised to the zero power is 1

y = x^0 is 1

Even any number raised to the power of 0 is 1.

 5555^0 =1

Well not every number. 0^0 is a bit of an exception. 0^0 is undefined and you for that reason you should be careful how you treat it. You should good it when you encounter it. The answer is controlled by circumstances.

That being noted, b^0 in general is 1.

The y intercept is (0,a)
