if you horizontally stretch the quadratic parent function f(x)=x^2 by multiplying by 1/2, what is the equation of the new function ? Please help :D
A: H(x)=2x^2
B:H(x)=1/4x^2
C:H(x)=x^2+1/2
D:h(x)=1/2x^2

I have studied a lot of math but I never heard of a parent function.
A, B, and C are wrong, and D is ambiguous. What are you taking, a course in nonsense?
D: h(x) = (1/2)x^2 We use parentheses to indicate what acts on what. You can not stand a spelling mistrake in math. A statement must have exactly one possible interpretation.
It seems like they threw some additional verbiage in there to try and distract you. Basically, the question is:
What is the function f(x) = x^2 divided by 2 if we relabel it as a function of some other variable.
In which case, h(x) = 1/2(x^2) or choice D.
Multiplying a parabola by a constant > 1 will make it more narrow.
Multiplying it by a fraction <1 will make it wider at the top.
