–18

–16

22

24

explain

The discriminant of the quadratic equation is:

                               24

Step-by-step explanation:

We know that for any quadratic equation of the type:

The discriminant of a quadratic function is denoted by D and is calculated by the formula:

Now here we are given a quadratic equation as:

which is written as:

i.e. we have:  a=5 , b=2 and c= -1

Now, the discriminant is calculated as:

              Hence, the discriminant is:

                             24

what are the statements

step-by-step explanation:

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
