Which of the following is the graph of the quadratic function y - x? +10x+16 ?
a. graph c
b. graph b
c. graph a
d. graph d

Find the vertex:

Determine if the parabola will open up or down:

Since the value of a is positive, the parabola will open upwards

Find the x and y intercepts:

Factor to find the x intercepts

(x+8)(x+2)

x + 8 = 0

x = -8

x + 2 = 0

x = -2

x intercepts:

x = -2

x = -8

Find the y intercept

Hence, C. Graph A best represents the quadratic function

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
