\[f(x)=5\sqrt{3+x^2}\text{ ? }\]

OpenStudy (anonymous):

yes

What is your first thought?

OpenStudy (anonymous):

im just confused never heard of a extreme value

OpenStudy (mathmale):

Here "extreme value" refers to either a "maximum" or a "minimum." Find the derivative of the given function and solve for the critical value (or values). Plot these on the x-axis of a set of coordinate axes. This will definie several intervals on the x-axis. Choose a representative number from each such interval. Plug that number into the derivative of f(x). Is the result + or - ? Know what to do next?

no @mathmale

Are you familiar with derivative? @xedwinvf67

OpenStudy (anonymous):

no sir i dont

geerky42 (geerky42):

Ok you do know what \(x^2\) looks like, right? What is extreme values for \(x^2\)?
