Answer:
y=|x+7|
Step-by-step explanation:
to move an absolute value equation to the left, all you have to do is add 7 to the inside of the absolute value:
y=|x+7|
We can check that this works, because the x-intercept moved from (0, 0) to (0, -7), meaning that the whole graph got translated 7 units to the left.
Q1: vertical shift of down 4: Indicated by the subtraction of 4 at the end of the function, and a horizontal shift of 2 unit left as indicated by the addition of 2 to the independent variable "x"
Q2: To stretch a function, you can just multiply it by the desired factor. Thus, the function g(x)=
Q3: g(x) =
Note that the initial point (2,0) has shifted down 1 and to the right 2. Subtracting 2 from x takes care of the horizontal shift of 2 to the right, and subtracting 1 at the end of the function produces a vertical shift of down 1.
Answer:
If the graph of a function f is known, it is easy to determine if the function is 1 -to- 1 . ... If no horizontal line intersects the graph of the function f in more than one point, then the function is 1 -to- 1 . A function f has an inverse f−1 (read f inverse) if and only if the function is 1 -to- 1 .

Answer:
90 and 8
Step-by-step explanation:
The question is : the sum of two numbers is 98 and their difference is 82 find the two numbers
Let two numbers are x and y.
Sum of two numbers is 98
x+y = 98 ....(1)
The difference of two numbers is 82.
x-y=82....(2)
Adding equation (1) and (2) we get :
x+y+x-y=98+82
2x=180
x=90
Put the value of x in equation (1)
90+y = 98
y = 8
Hence, the two numbers are 90 and 8.
