A parabola has x-int of (-8,0) and (4,0) and a minimum value of -9 in intercept form

Mathematics

Answer:

The function is  1/4x^2  + x - 8

Step-by-step explanation:

In Factor form the function  is

a(x + 8)(x - 4)    where a is a constant to be found.

= a( x^2 + 4x - 32)  Note the coefficient of x is positive because the function has a minimum value.

The line of symmetry is x = (-8+4)/2 = -2.

So the minimum value  will be the  value of f(x) when x = -2, so we have the equation

a(-2+8)(-2-4) = -9

-36a = -9

a = 1/4.

WHOEVER ANSWERS FIRST GETS BRAINLIEST!!!!
Ratling [72]

Answer:

A, C and E are true.

Step-by-step explanation:

The domain is a set of natural numbers.

The recursive formula is correct:

When x = 1, f(x) = 4 and f(x + 1) = f(2) = 3/2 f(x) = 3/2 * 4 = 6.

It is also true for the other points on the graph.

D is  incorrect.

E is correct exponential growth with the formula  4(3/2)^(x-1).
