Answer:
9
Step-by-step explanation:
negative times a negative is a positive. Negative three squared is 9.
Answer:
- reflection over the x-axis
- translate right 2 units
- translate down 3 units
Step-by-step explanation:
Horizontal translation of the graph of a function is accomplished by replacing x with (x-h) for translation h units to the right. Vertical translation of the graph is accomplished by adding the amount of translation to the function value: f(x)+k translates the graph k units upward.
Reflection of a function over the x-axis is accomplished by changing the sign of every function value: -f(x).
<h3>Application</h3>
We observe that f(x) has been transformed by ...
- multiplying by -1 to get -f(x)
- replacing x with (x -2) to get -f(x -2)
- adding -3 to the function value to get -f(x -2) -3
The effect of these transformations is (correspondingly) ...
- reflection over the x-axis
- translate right 2 units
- translate down 3 units
__
The attached graph shows a function f(x) (red) and the transformed function (blue).
Answer:
y = $1.25x
Step-by-step explanation:
Given that :
Profit made per sale = $1.50
Number of sales made on hottest day of summer = 125 ; Profit made = $187. 50
Let profit Made = y
Number of snowballs sold = x
Profit made = profit made per snowball sold * Number of snowballs sold
y = $1.25x
$187.50 = $1.25(125)
