Which is the equation of a parabola with vertex (0,0), that opens to the right and has a focal width of 8? a. y^2=8x b. y^2=-8x c. x^2=8y d. x^2=-8y

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

x= 3^y
