Answer 2

I think the 135 should be 125?

Answer 3

Yeah, my bad. lol

Answer 4

well just substitute a few values...

it can't be (d) as 5 = 1 + 5 nope after substituting the point (1, 5)

and in (b) substitute (1, 5) so you get y = 5*1 so that works
try (2, 25) 25 = 5*2 nope 25 doesn't equal 10 so its not b

try (a) substitute (1, 5) 5 = 1^5 nope you get 5 = 1 which isn't true

look at (c) does 5 = 5^1....?
25 = 5^2...?

I'll let you decide
