extreme 2t^2+7t+9

Solution

extreme points

2 t^{2} + 7 t + 9

Solution

Minimum (- \frac{7}{4}, \frac{23}{8})

Solution steps

f^{'} (t) = 4 t + 7

Find intervals:

Decreasing

: - \infty < t < - \frac{7}{4},

Increasing

: - \frac{7}{4} < t < \infty

Plug

t = - \frac{7}{4}

into

2 t^{2} + 7 t + 9 : \frac{23}{8}

Minimum (- \frac{7}{4}, \frac{23}{8})
