Answer:

The correct option is 3.

Step-by-step explanation:

To find the slope of a line Ava wrote the expression

$m=\frac{4-2}{3-1}$ ..... (1)

The formula to find the slope is

$m=\frac{y_2-y_1}{x_2-x_1}$ .... (2)

On comparing (1) and (2), we get

$x_1=1, y_1=2$

$x_2=3, y_2=4$

It means the value of y is 2 at x=1 and the value of y is 4 at x=3.

Therefore table 3 represents the Ava's line and option 3 is correct.

What is the change that occurs to the parent function f(x) = x^2 given the function f(x) = 2(x + 2)^2 + 1.

Answer:

The graph is stretched by a factor of 2, moves 2 units to the left, and 1 unit up.

Step-by-step explanation:

The base of the quadratic function is

$f(x) = {x}^{2}$

We can transform this function to look narrower or wider.

Looking narrower is termed a stretch.

This happens when a>1

Looking wider is termed a compression.

This happens when 0<a<1

We can also

$g(x) = a {(x + h)}^{2} + k$

+h moves the parent graph to the left by h units

-h moves the parent graph to the left by h units.

+ k moves the parent function up by k units

- k moves the parent function down by k units.

The change that occurs to

$f(x) = {x}^{2}$

given

$f(x) = 2( {x + 2)}^{2} + 1$

is that, the graph is stretched by a factor of 2, moves 2 units to the left, and 1 unit up

Therefore the last choice is the correct answer.

Prove that A is in the subset B if P(A) is in the subset P(B)

natima [27]

Show that if p(a) ⊂ p(b) then a ⊂ b.

<span>I will assume p() means power set. </span>

<span>proof: let x∈a, then {x} ∈ p(a) and so by hypothesis {x} ∈ p(b). However {x} could not be in p(b) unless x∈b. This shows that each element of a is an element of b and hence a ⊂ b.
