Let's compare the given function with the model for a quadratic equation:

$\begin{gathered} f(x)=ax^2+bx+b \\ a=2,b=12,c=-6 \end{gathered}$

Since the value of a is positive, the parabola has its concavity upwards, and the function has a minimum value.

The minimum value can be found calculating the y-coordinate of the vertex:

$\begin{gathered} x_v=-\frac{b}{2a}=-\frac{12}{4}=-3 \\ \\ y_v=2\cdot(-3)^2+12\cdot(-3)-6 \\ y_v=2\cdot9-36-6^{} \\ y_v=-24 \end{gathered}$

Therefore the minimum value is -24.

Answer:

y = -6x — 13

Step-by-step explanation:

use y = mx + b equation and plug in what you know.

5 = -6(-3) + b —> solve for b

b = -13 —> plug in what you know into y=mx+b

ANSWER: y = -6x — 13
