HELP ASAP f(x)=x² what is g(x)?

Mathematics
1 answer:
murzikaleks [220]2 years ago
4 0

Just by comparing the plots of f(x) and g(x), it's clear that g(x) is just some positive scalar multiple of f(x), so that for some constant k, we have

g(x) = k • f(x) = kx² = (√k x)²

The plot of the transformed function g(x) = (√k x)² passes through the point (1, 4), which means

g(1) = (√k • 1)² = 4

and it follows that k = 4. So g(x) = 4x² = (2x)² and B is the correct choice.

Solve the following pair of simultaneous:<br><img src="https://tex.z-dn.net/?f=%205x%20%2B%202y%20%3D%20%20-%202%20%20%20%20%20%

Answer:

x = -2 , y = 4

Step-by-step explanation:

given:

5x + 2y = -2                            <em>*4</em>

4x + 3y = 4                             <em>*5</em>

Solving simultaneously,

    20x + 8y = -8 ....eq 1

(-)  20x +15y = 20  ...eq 2

.............................................

-7y = -28

y = -28 / -7

y = 4

  • if y = 4

using equation 2,

20x +15(4) = 20

20x = -40

x = -2

Students were asked how many pairs of shoes they owned. Their responses were 8, 2, 1, 5, 7, 6, 2, 2, 8, and 3.
IRINA_888 [86]

Answer:

4.4

Step-by-step explanation:

The mean is the sum of the data divided by the number of data values.  so add them all together and then divide by how many numbers you added together.

Here is an example 1,3,4,5,7 so add 1+3+4+5+7=20 then you divide 20 by 5 and the mean is 4 for this example.
