It’s represent school on the graph
Answer:
the answer is C because both the x and y values are multiplied by 4. You cant dilate something by a scale factor of a negative number, so A can be crossed out. B and D only dilate one value of the dilation, so they are incorrect. So C is the only answer.
no because yes.

The answer is <span>1) ± √x+81
</span>
Step 1: Substitute y for f(x). <span>
Step 2: </span>Since every (x, y) has its partner (y, x)y switch x and y.
Step 3: <span>Solve for y.
Step 1.
The function is: f(x) = x</span>² - 81
Substitute y for f(x): y = x² - 81
Step 2.
Switch x and y: x = y² - 81
Step 3.
Solve for y (which is now f⁻¹(x)): f⁻¹(x) = y
x = y² - 81
y² = x + 81
y = +-√(x+81)
Therefore, the choice 1) is correct.
<h3>25 =∣x - 15∣</h3>
<em>Swap the sides so that all the terms of the variables are on the left side.</em>
<h3>∣x - 15∣= 25</h3>
<em>Use the definition of absolute value.</em>
<h3>x - 15 = 25</h3><h3>x - 15 = -25</h3>
<em>Add 15 to both sides of the equation.</em>
<h3>x = 40</h3><h3>x = -10</h3>
