Which graph represents the function f(x)=-x2+5?

The graph of given function is shown below.

Step-by-step explanation:

The given function is

            .... (1)

We need to find the graph of the function.

The vertex form of the quadratic function is

           .... (2)

On comparing (1) and (2) we get

It means the vertex of the function is (0,5).

The table of values is

x                 y

-2               1

-1               4

0              5

1               4

2              1  

Plot all ordered pairs on a coordinate plane and connect them by a free hand curve.

The graph of given function is shown below.

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
