Given the graphed function below, which of the following ordered pairs are found on the inverse function?
2 answers:
Answer:
Step-by-step explanation:
Answer with explanation:
Suppose, y=√x ,is a polynomial function.Here Domain =[0,∞)
→ y²=x
Range =(-∞,∞)
To find the inverse of the given function,replace x by y, and y by x in the original function.
So, x=√y, is the equation of inverse function.
if a point (x,y) lies on original function, then point (y,x) lies on the inverse function.
The graphed function given below passes through points
(1,0),(0,-1),(-2,-9),(2,7),and (-1,-2).
So, inverse function of the above function will pass through
(0,1),(-1,0),(-9,-2),(7,2),and (-2,-1).

Answer:
The ratio of the areas of the smaller rectangle to the larger rectangle is
Step-by-step explanation:
we know that
if two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z-----> the scale factor
x-----> the area of the smaller rectangle
y----> the area of the larger rectangle
so
substitute the values
simplify
That means, the area of the larger rectangle is 9 times the area of the smaller rectangle
------> the scale factor
That means, the dimensions of the larger rectangle is 3 times the dimensions of the smaller rectangle
