What is the value of the discriminant of f?
How many distinct real number zeros does f háve?
Help ASAP

Step-by-step explanation:

The discriminant is part of the quadratic formula.  If the value of the discriminant is less than 0, you have 2 imaginary solutions; if the discriminant is equal to 0, you have 1 real solution; if the discriminant is greater than 0, you have 2 real solutions.

The discriminant is , which for us, looks like this:

which simplifies to -63.  That means that the solutions are imaginary...not real at all.  So in answer to your question, there are no real zeros at all.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
