Question

Use the First Derivative Test to determine the local extreme values of the function and identify any absolute extrema.

y=2x^4 + 1

Answer 1

you can't need calculus for this
\[y=2x^4+1\] is a parabola that opens up, which a minimum value of 1 when x = 0

Answer 2

But how do i use the First Deriv test?

Answer 3

\[y'=8x^3\]which is only 0 if \(x=0\)

Answer 4

oh. alright. thanks
