Answer:
Output, Range
Explanation:
Lets try to understand all the 5 terms, so we can find out our answer.
Domain is the set of allowed x-values for a function, for which a function is defined for. Certainly not synonymous to y-value.
Output is what we get from a function when we input (x) a value. Hence, we can say we put x value and get y value as output. So, this is synonymous.
Range is the set of allowed y-values for a function, for which that function is defined. Certainly this is a synonym for y-value.
Function is simply the mapping, or rule, between x and y values. Not a synonym for y-value.
Input is what we put into the function, so that is x value. Certainly this is not synonym for y-value.
Output & Range are our answer.s
