Question

Use the parabola tool to graph the quadratic function f(x)=2x^2−8x+2.

Answer 1

(0, 2) and (2, -6), among other points!

Explanation:

If all you need is two points, choose two values for x and plug them into the formula for the function.

`x=0 \Rightarrow 2(0)^2-8(0)+2=2` so the point (0, 2) is on the graph.

`x=2 \Rightarrow 2(2)^2-8(2)+2=-6` so the point (2, -6) is on the graph.
