Answer:
A function is a rule that assigns to each input exactly one output.
Step-by-step explanation:
If you have more than one of the same inputs for multiple outputs, it would create a vertical line at somepoint on your line.
I will refer to the graphs as 1 - 6, starting at the top and going down. 6 is not present, though I will still include it by process of elimination.
All real numbers less than -7 or odd numbers between -7 and 7, exclusive. = Graph #6
All real numbers except -7. = Graph #2
Numbers divisible by 4 between -10 and 10. = Graph #4
All real numbers up to and including -1 or more than 1. = Graph #1
All real numbers between -7 and -4, inclusive, or between -1 and 1, exclusive. = Graph #3
Prime numbers between -10 and 10. = Graph #5
Hope this helps!
The ratio is 2/1. The combined number for pennies and dimes together is 48 since 32 + 16 = 48. You then put 48 and 24 into this ratio: 48/24. Simplify this ratio to get 2/1.
You would have $660. The trick for 10% of something is to move the decimal one place to the left. The decimal is “hidden” to the right of the last 0. Add that interest on to get your answer!! Good luck!
Option 1: At x = 0,
f(x) = 128(0.5)^0 = 128(1) = 128 (not satisfy the ordered pair which is (0,128))
Option 2: At x = 1,
f(x) = 128(0.5)^1 = 128(0.5) = 256 (not satisfy the ordered pair which is (1,256))
Option 3: At x = 3,
f(x) = 128(0.5)^3 = 128(1/2)^3 = 128(1/8) = 16 (satisfy)
Hence, the answer is Option 3.
