Interpreting the question as "evaluate f(x) = -x2 + 5 for x = 4". This is the same as asking "what is f(4)". To evaluate f(4) just replace each instance of the x in the definition of f(x) by the number 4: f(4) = -42 + 5. The result is -11.
Yes.
in general, the y-intercept of the function f(X)= axb^x is the point__.
False
f(x) = bX is not an exponential function so the question makes no sense.
x = ¼x^4 + 4x + k where k can be any number
B- It is a many-to-one function
It is a many to one function (APEX)
Yes.

You need to clarify the function AND provide an interval.
f(x)=5x+2
- 2 makes this zero and provides the vertical asymptote. So, from - infinity to - 2 and from - 2 to positive infinity
If you are talking about f(x) then yes it is the same as y
The function f(x) = 3x + 2 can take any real value, so the question does not seem to make any sense.
