Consider the following quadratic function f(x)= -2x^2+12x+32=0 select all the statements that are true for the function

The answer to your question is

a) 400

b) The function has two real solutions (-2 and 8)

Step-by-step explanation:

Process

1.- Discriminant = b² - 4ac

                         = 12² -4(-2)(32)

                         = 144 + 256

                        = 400

2.- Solutions (using the general formula)

                   x =

                   x =

                   x =

   x₁ =

   x₂ =

This function has two real solutions (-2, 8)

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
