Answer: The graph is attached.
Step-by-step explanation:
By definition, the line intersects the y-axis when .
Then, in order to find the y-intercept, substitute into the equation and solve for "y":
By definition, the line intersects the x-axis when .
Then, in order to find the x-intercept, you can substitute into the equation and then you must solve for "x". Then you get:
Knowing that the line passes through the points and
, you can graph it (The graph is attached).
Given:
The point (15,-11) is on the graph of a one-to-one function f(x).
To find:
The a point on the graph of .
Solution:
We know that, if the points on the graph of a one to one function are given by (x,y), then the points on the graph of its inverse function are given by (y,x).
In the point (15,-11).
x-coordinate = 15
y-coordinate = -11
In the inverse function,
x-coordinate = -11
y-coordinate = 15
Therefore, the required point on the graph of is (-11,15).
