We can use the slope formula for each of these.
1. 5 - 1 / 4 - 2
4 / 2
2
The slope is 2, and it is rising because it is positive.
2. -5 - 0 / 3 - (-1)
-5 / 4
The slope is -5/4, and it is falling because it is negative.
3. 1 - 1 / -3 - 2
0 / -5
0
The slope is 0, and it is a horizontal line. The value of y is not changing per value of x.
4. -5 - 2 / -1 - (-1)
-7 / 0
Undefined
The slope is undefined because it fails the vertical line test.
Answer:
Option (1)
Step-by-step explanation:
From the graph attached,
Points connecting the graph 'g' are (-5, 4), (-2, 1), (0, -1), (4, -2).
Since, rule to get the points lying on the graph of the inverse of the given function is,
(x, y) → (y, x)
If (x, y) is a point on function 'g' then (y, x) will lie on the inverse of the given function.
By the given rule, points on will be,
(4, -5), (1, -2), (-1, 0), (-2, 4)
Therefore, value of the inverse function at x = 4 will be,
y = = -5
Option (1) will be the correct option.
