Use the parabola tool to graph the quadratic function f(x)=2x^2−8x+2.
garik1379 [7]

Answer:

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

Step-by-step 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.

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

Based on the situation above the inequality will he use to contradict the assumption is <span>
4:10 ≠ 6:14</span>
if DE is parallel to BC
then
4: (4+5) = 6 : (6 + 8)

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = -7x + 6

y = -10x

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

  1. Substitute in <em>y</em>:                   -10x = -7x + 6
  2. Add 10x to both sides:      0 = 3x + 6
  3. Isolate <em>x</em> term:                    -6 = 3x
  4. Isolate <em>x</em>:                             -2 = x
  5. Rewrite:                              x = -2

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define equation:                    y = -10x
  2. Substitute in <em>x</em>:                       y = -10(-2)
  3. Multiply:                                  y = 20
