1) Identify the roots of the quadratic function. What is the product when the roots are multiplied? A) −1 B) −6 C) 0 D) 1

D) 1

Step-by-step explanation:

Quadratic expression:-

Any equation that can be expressed in the form

where a,≠ 0 is called a quadratic equation in 'x' Here a, b ,c are called co-efficient.

Example: the quadratic expression is

here a= 1 ,b=1 and c=1

α and β are roots of the quadratic equation

sum of the two roots are α+β = -b/a = -1

product of two roots are αβ = c/a =1

There fore the product of two roots are equal to one

B. -6

Step-by-step explanation:

for usatestprep

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
