Answer:
1. the range of f^-1(x) is {10, 20, 30}.
2. the graph of f^-1(x) will include the point (0, 3)
3. n = 8
Step-by-step explanation:
1. The domain of a function is the range of its inverse, and vice versa. The range of f^-1(x) is {10, 20, 30}.
__
2. See above. The domain and range are swapped between a function and its inverse. That means function point (3, 0) will correspond to inverse function point (0, 3).

3. The n-th term of an arithmetic sequence is given by ...
an = a1 +d(n -1)
You are given a1 = 2, a12 = 211, so ...
211 = 2 + d(12 -1)
209/11 = d = 19 . . . . . solve the above equation for the common difference
Now, we can use the same equation to find n for an = 135.
135 = 2 + 19(n -1)
133/19 = n -1 . . . . . . . subtract 2, divide by 19
7 +1 = n = 8 . . . . . . . . add 1
135 is the 8th term of the sequence.
D. It has a positive slope and negative y- intercept.
Step-by-step explanation:
2y -3x = -4
We can rewrite the equation in the form of y = mx+ b where m is the slope and b is the y - intercept as,
2y = 3x- 4
Dividing all the terms by 2, we will get,
2y/2 = 3x/2 - 4/2
y = (3/2)x -2
So the slope is 3/2 which is positive and y-intercept is -2 which is negative.
Answer:
d) 3/8
Step-by-step explanation:
0, 1/8, 2/8, 3/8, 4/8, 5/8, 6/8, 7/8, 1
Hope this helps!
Answer:
x-intercept=(-1,0) y-intercept =(0,-3)
Step-by-step explanation:
False. If the area is 0 that means there is nothing there, therefore the area of a polygon cannot be zero.
