What is the axis of symmetry of the function f(x)= -(x+9)(x-21)

Mathematics
1 answer:
Vinil7 [7]3 years ago
6 0

Answer:

The axis of symmetry is x = 6

Step-by-step explanation:

To find this, first find the two x-intercept values and then take the average. This will always be the line of symmetry.

x + 9 = 0

x = -9

x - 21 = 0

x = 21

Now take the average of these two numbers.

(-9 + 21)/2

12/2

| 2p -1 | =45, what are the values of p?
Alex73 [517]

Answer:

p = 23       and p = -22

Step-by-step explanation:

| 2p -1 | =45

Absolute value equations have 2 solutions, one positive value and one negative

2p-1 = 45    and 2p-1 = -45

Add 1 to all sides

2p-1+1 = 45+1    and 2p-1+1 = -45+1

2p = 46                        2p = -44

Divide by 2

2p/2 = 46/2    and   2p/2  = -44/2

p = 23       and p = -22

Write the equations after translating the graph of y = |x|: one unit up,
Tatiana [17]

Answer:

g(x) = |x| + 1

Step-by-step explanation:

Given

y = |x|

Required

Translate 1 unit up

Start by replacing y with f(x)

f(x) = |x|

To translate an the graph of an absolute function upward, you make use of the formula;

g(x) = f(x) + k

Where k is the number of units

In this case; k = 1

Hence;

g(x) = f(x) + k

Substitute k = 1

g(x) = f(x) + 1

Substitute  f(x) = |x|

g(x) = |x| + 1

<em>Hence, the resulting equation is </em>g(x) = |x| + 1<em></em>
