Having Real roots mean the discriminate is,

• greater than 0

• Less than 0

• Equal to 0

Having imaginary roots mean the discriminate is

• Greater than 0

• Less than 0

• Eqaul to 0

The graphs above show the discriminates as

• greater than 0, less than 0, equal to 0

• less than 0, equal to 0, greater than 0

• less than 0, greater than 0, equal to 0

• equal to 0, less than 0, greater than 0

Using the quadratic equation, for this function f(x)=3x²+4x−8 step one is to let; A=3, B=4, C=8

• True

• False, A=-3, B=4, C=8

• False, A=3, B=-4, C=-8

• False, A=3, B=4, C= -8

• False, A=3, B=-4, C=-8

Using the quadratic equation, for this function f(x)=3x²+4x−8 the discriminate indicates we will have

• 2 real roots and 0 imaginary roots

• 2 imaginary roots and 0 imaginary roots

• 1 real root and 1 imaginary root

• 1 real root and 0 imaginary roots

• 1 imaginary root and 0 real roots
