F(x)=-4x2+12x-9
What is the value of the discriminate of f?

How many x-intercepts does the graph of f have?

The discriminant of a quadratic is the expression inside the radical of the quadratic formula. b-4(ac)

Substitute in the values of a, b, and c

12- 4 (-4 .-9)

Simplify each term.

Raise 12 to the power of 2

144 - 4 (-4 .-9)

Multiply -4 by -9

144-4 x 36

subtract 144-44

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

answer: 414,377,008
