Question

Find $\frac{dy}{dx}$ and $\frac{d^2y}{dx^2}$. $x = t^2 + 1$, $y = t^2 + 5t$ $\frac{dy}{dx} = \frac{2t + 5}{2t}$ $\frac{d^2y}{dx^2} = \frac{-5}{2t^2}$ Find the values of $t$ for which the graph described by the parametric equations is concave up. (Enter your answer using interval notation.) $t < 0$

          Find $\frac{dy}{dx}$ and $\frac{d^2y}{dx^2}$.

$x = t^2 + 1$, $y = t^2 + 5t$

$\frac{dy}{dx} = \frac{2t + 5}{2t}$

$\frac{d^2y}{dx^2} = \frac{-5}{2t^2}$

Find the values of $t$ for which the graph described by the parametric equations is concave up. (Enter your answer using interval notation.)

$t < 0$

Find (dy)/(dx) and (d^2y)/(dx^2).

x = t^2 + 1, y = t^2 + 5t

(dy)/(dx) = (2t + 5)/(2t)

(d^2y)/(dx^2) = (-5)/(2t^2)

Find the values of t for which the graph described by the parametric equations is concave up. (Enter your answer using interval notation.)
