A. 3/4 • 7/8 = 21/32 < 7/8
B. 1 1/3 • 9/10 = 2 1/5 > 9/10
C. 3/4 • 7/8 = 21/32 < 7/8
D. 7/8 • 9/10 = 17/20 < 9/10
A is the correct answer.
(-5uv)^4
^4 means to the power of four
Answer:
- domain: -∞ < x < ∞
- range: -2 ≤ y < ∞
Step-by-step explanation:
First of all, it is useful to understand what the graph is telling you. The curve tells you for input values between about -6.5 and -3.5, the output values are between -2 and about 7.5.
The arrow on the left end of the curve mean that as x goes more negative than -6.5, the y-value goes more positive than 7.5. The graph tends toward (-∞, ∞).
The arrow on the right end of the curve mean that as x goes more positive than -3.5, the y-value goes more positive than 7.5. The graph tends toward (∞, ∞).

The question asks about the domain and range of the function.
The domain is the <em>horizontal</em> extent of the graph, a description of all possible input values for which the function is defined. Here, that is all possible values of x: the domain is -∞ < x < ∞.
The range is the <em>vertical</em> extent of the graph, a description of all possible output values from the function. Here, the function does not produce any outputs lower than -2, but it can give any value from -2 on upward: the range is -2 ≤ y < ∞.
Answer: 41
Explanation: Use the equation. If you put the x value, which is 5, into the equation, you can solve.
4(5)+21
4 x 5 is 20
20+21=41
hope this helps!!
