Function or not? For every input (value between the parentheses), find the output using the given function. Secondly, tell whether the relation is a function or not. Remember that if the same input has two different outputs, the relation is not a function.
Ex: {(2, 14), (3, 16), (4, 14), (5, 16), (2, 20)}
Did you notice that 2 has two outputs: 14, and 20..
Note that if two inputs have the same output, the relations is a function:
Ex: {(2, 14), (3, 16), (4, 14), (5, 18), (6, 20)}, Example f(x) = √ + Domain is only the positive real numbers
f(1) = √ + = √ + = √
f(0) = √ + = √ + = √ = 1
f(3) = √ + = √ + = √

my acc plz

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
