Explanation:
If y has an exponent of 2, 4, 6, etc (basically any even number) then it leads to having inputs with multiple outputs.
Consider something like y^2 = x. If x = 100, then y = 10 or y = -10 are possible. A function can only have exactly one y output for any valid x input. Similar issues happen for things like y^4 = x and so on. So this is why A and C are not functions.
The other equations do not have y values with such exponents, so we can solve for y and have each x input lead to exactly one y output. Therefore, they are functions.
Answer:
She will need to fill it eight times
Step-by-step explanation:
There are 8 ounces in one cup. So, 16 ounces is equal to two cups.
Multiply 2 by 4 to get the answer
For an equal number of servings, the bananas will have three times as much sugar.
To put it in perspective:
When we have one serving of each fruit, the carrot will give you 5 grams of sugar whereas banana will give you 15 grams.
Hope this helps!
