Find the discriminant for each quadratic function below. Then list the number of zeros/solutions for each quadratic function. 1) 4x^2+10x-16=0
Discriminant
Number of Zeros

2) -16x^2-7x+3=0
Discriminant
Number of zeros​

Step-by-step explanation:

The discriminant is found in

which is part of the quadratic formula. In

, a = 4, b = 10, c = -16. Filling in for the discriminant:

It's positive so we know we have real roots; it's not a perfect square, so our solutions are 2 complex rational.

In , a = -16, b = -7, c = 3. Filling in for the discriminant:

It's positive and not a perfect square so the 2 solutions are complex rational

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
