Which shows the correct substitution of the values a, b,and c from the equation 0=4x^2+2x-1 into the quadratic formula below

Given quadratic equation :

Let us apply standard quadratic form

We know, quadratic formula

a = 4

b = 2

c= -1

Now we plug in all the values in quadratic formula

.

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
