What are the questions on 7 and 8?
Answer:
<u>Given function</u>
#15 Find the inverse of h(x)
<u>Substitute x with y and h(x) with x and solve for y:</u>
- x = 2y - 1
- 2y = x + 1
- y = 1/2x + 1/2
<u>The inverse is:</u>
#16 The graph with both lines is attached.
The x- and y-intercepts of both functions have reversed values.
#17 Table of the inverse function will contain same numbers with swapped domain and range.
<u>Initial look is like this:</u>
- <u>x | -3 | -2 | -1 | 0 | 1 | 2 | 3</u>
- h⁻¹(x) | -1 | | 0 | | 1 | | 2
<u>The rest of the table is filled in by finding the values:</u>
- <u>x | -3 | -2 | -1 | 0 | 1 | 2 | 3</u>
- h⁻¹(x) | -1 | -0.5 | 0 | 0.5 | 1 | 1.5 | 2
Answer:
13
Step-by-step explanation:
So first Subtract 100 from 250. Since you are trying to find out the amount of hours, you don’t need the tips to count.
The next step is too either do the equation 150 divided by 11.50 or you can multiply 11.50 by 13.
it’s not fourteen because 149.5 is closer to 150 then 161
Hope this helps
Answer:
12
Step-by-step explanation:
The common ratio is 1.5. If the input is 8, the output has to be 12.
Answer:
(a) y = ±(√x)/2
Step-by-step explanation:
You want to find y such that ...
x = f(y)
x = 4y^2 . . . . . . . put in the expression for f(y)
x/4 = y^2 . . . . . . .divide by 4
±√(x/4) = y . . . . . take the square root
y = ±(√y)/2 . . . . . simplify
