hello i simplified this equation to be f(x)=x^4-2x+16. i believe the y intercept is (0,16)

Answer:

(0,7)

Explanation:

So we have:
f(x)=x+2x^(3)-2x+7 .

The y-intercept is the point where the y-axis is crossed (or intercepted, if you will) by the function. Since the y-axis is located where x=0, we can find the y-intercept by letting x=0.


f(x)=x+2x^(3)-2x+7


f(0)=0+2(0)^(3)-2(0)+7=7

So the y-intercept is at (0,7)
