Complete a table with at least 5 points then graph the following quadratic on the coordinate plane. Identify all zeros.y = -2x2

Anna [14]

Answer:

See attached

Step-by-step explanation:

Given function:

y = -2x² + 5x + 8

Table and graph are attached

Zeros are included in the graph

<u>Zero's are obtained:</u>

x = 0 ⇒ y = 8

y = 0 ⇒ Solving quadratic equation

-2x² + 5x + 8 = 0
x = (-5 ± √(25 + 2*4*8))/-4
x = 3.608
x = -1.108

So zeros are (0, 8), (3.608, 0) and (-1.108, 0)

What is the answer to 12x^7 over 3x

Darina [25.2K]

Simple, what you're basically doing is simplifying,

$\frac{ 12x^{7} }{3x}$

well, you have 3x and you have $12x^{7}$

12/3=4

and you can "cancel" out an x, making your answer,

$4x^{6}$ .
