Answer:
-5, 5
Step-by-step explanation:
The line in this problem can be written in the form
(1)
where:
is the slope
q is the y-intercept
We know that the line passes through the point (-2,5), so substituting these values into eq.(1), we find the value of the y-intercept:
So the equation of the line is
(2)
Now we know that point A has coordinates
A(x,3)
So by substituting into eq.(2), we find the missing x-coordinate:
Similarly, point B has coordinates
B(-2,y)
so substituting into eq(2), we find the missing y-coordinate:
Answer:
f^-1(x) = cuberoot(x+5)

Step-by-step explanation:
To find an inverse function:
first, write y in place of f(x)
second, switch the x and y.
third, solve for y.
last, replace y with inverse function notation, f^-1(x)
