A function is when the y value doesn't repeat. the x can repeat infinitely but the y can not to be a function.
The y value is the second number in each set and it doesn't repeat so this IS a function
Answer:
22
Step-by-step explanation:
it shows in the image that AC and AB are isosceles so 2x - 24 would be equal to x - 2
2x - 24 = x -2 ➡ x = 22
(2x)+3 is the correct answer. Please mark BRAINLIEST

Answer:
20. y = 3·3^x
21. y = (1/3)^x
Step-by-step explanation:
These exponential functions can be written in the form ...
y = a·b^x
where a is the value of y when x=0, and b is the common ratio between terms that have x different by 1.
__
20. The ratio is 9/3 = 3; the multiplier is 3 (the value of y when x=0), so the function is ...
y = 3·3^x
__
21. The ratio is (1/3)/1 = 1/3; the multiplier is 1, so the function is ...
y = (1/3)^x
_____
<em>Alternate solution</em>
Each of these can be written in a more compact form:
20: y = 3^(x+1)
21: y = 3^(-x)
