what is the equation of the graph that represents the parent function f(x) = x4 stretched vertically by a factor of 2, and then shifted down 3 spaces

f(x) = 2x^4 - 3

Step-by-step explanation:

First multiplying by 2 giving f(x) = 2x^4 stretches it vertically by factor 2.

Then subtract 3 to move it down 3 units:

f(x) = 2x^4 - 3.

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
