It's the first one because the other three go pasted -6 which would make the problem not true.
Answer:
A) f(x) = 15x + 25; f(0) = 25
Step-by-step explanation:
x represents the amount of extra services, and 15x respresents the amount paid for all of the services. 25 represents the initial fee. f(0)=25 means that it cost $25 for a haircut with no extra services.
Let's say you have a haircut with two extra services. You would replace the x in the equation with the number of extra services, 2 in this case.
f(2)=15(2) + 25
f(2)=30+25
f(2)=55
It would cost $55 for a haircut with 2 extra services.

Answer:
no, because for x=-3, y would have to be -31
Step-by-step explanation:
boy oh boy (or girl oh girl) - you wrote this in a horrible, horrible format.
I can only guess what your problem and the fitting answer would be.
y = -2×x^2 + 3×x - 4
-4 = -2×(-3)^2 + 3×(-3) - 4
-4 = -2×9 - 9 - 4
-4 = -18 - 9 - 4
-4 = -31
and that is wrong. for (-3,-4) to be on the graph of the function, y would have to be -4 when using x=-3 in the function. but y = -31 for x= -3.
