given the table of values below, which of the following ordered pairs are found on the graph of the inverse function?
2 answers:
Answer:
Option A. is the correct option.
Step-by-step explanation:
As per table given in this question values of the function has been given as
f(x) = -3 for x = -2
We can rewrite the function as f(-2) = -3
As we know inverse of the function means
or inverse function g(-3) = -2
and the ordered pair for the inverse function will be (-3, -2)
Similarly other ordered pairs for the inverse function given will be
(3, -1), (9, 0), (15, 1), (21, 2)
Therefore, the ordered pairs will be (-3, -2), (3, -1), (9, 0), (15, 1), (21, 2)
Option A is the right option.

Answer:
Yes, Cora is correct.
The equation of line with point (2,6) and slope of line (-1/3)
is x + 3y - 20 = 0
Step-by-step explanation:
Yes, the equation of a line can be written using a point and a slope of the line equation.
Cora has used the POINT SLOPE FORMULA, to represent the line equation.
In <u>Point Slope formula</u>:
The equation with slope m and points (x0,y0) can be written as:
(y-y0) =m (x-x0)
Here, the point (x0,y0) = (2,6)
and slope m = (-1/3)
So, the equation can be written as:
Hence, the equation of line with point (2,6) and slope of line (-1/3)
is x + 3y - 20 = 0
