## anonymous one year ago What is the relative maximum and minimum of the function? f(x) = 2x^2 + 28x - 8 A. Minimum Value: -106 Range y > -106 B.Minimum Value: -7 Range y > -7 D.Minimum Value: 7 Range y > 7

$f(x)=2x ^{2}+28x-8$

3. SolomonZelman

minimum is the vertex in this case. (it doesn't have an abd max)

4. anonymous

how do i find the vertex? @SolomonZelman

5. DecentNabeel

A. Minimum Value: -106 Range y > -106

6. anonymous

how did you find that? I am just wondering so I can try and solve similar equations in the future @DecentNabeel

7. DecentNabeel

fist find the stationary.. $\mathrm{Find\:the\:stationary\:points}:\quad x=-7$

8. DecentNabeel

then find the.. $\mathrm{Find\:the\:monotone\:intervals}$

9. DecentNabeel

then.. $\mathrm{Identify\:the\:extreme\:points}:\quad \mathrm{Minimum}\left(-7,\:-106\right)$
