Answer:

C and B.

Step-by-step explanation:

f(x) = 4 - x^2.

The degree of f(x) is 2, which means it is a quadratic graph. The coefficient of x^2 is negative, which means the curve is pointing downwards. The only curve that satisfies this is Graph C.

f(x) = 2^x + 5.

Notice that 2^x is positive for all real values of x. Therefore the answer is Graph B.

A number, one-fourth of that number, and one-third of that number are added. The result is 38. What is the original number?

Hatshy [7]

Answer:

Step-by-step explanation:

Let 12x represent the original number.

One fourth of that number can be represented by 3x, and one third of the number can be represented by 4x.

Create an equation that sets this equal to 38, and solve for x:

12x + 3x + 4x = 38

19x = 38

x = 2

The original number is represented by 12x, so plug in 2 as x:

12(2)

= 24

So, the original number is 24.

What is the vertex A,B,C or D

matrenka [14]

(C) (-2, -36) . . . . . . is the appropriate choice

_____
An easy way to tell is to let a graphing calculator show you.

Or, you can rearrange the equation to vertex form.
f(x) = 5(x² +4x) -16
= 5(x² +4x +4) -16 -5*4 . . . . complete the square
= 5(x +2)² -36
So, the vertex is (-2, -36).
