Answer:
The relation is <u>not</u> a function.
Step-by-step explanation:
A function is a relation in which no two ordered pairs have the same input and different outputs. Whenever you're trying to determine whether a given relation is a function, observe whether each input corresponds with <u><em>exactly</em></u> one output.
In this case, the answer is no. The input value of 10 corresponds with two output values, 4 and 20. It only takes one input value to associate with more than one output value to be <u>invalid</u> as a function.
Therefore, the given relation is <em><u>not</u></em> a function.

Answer:
The answer is 17
Step-by-step explanation:
<h3><u>Given</u>;</h3>
- a² – 4b + 2c
- a = 1, b = (-3) and c = 2
<h3><u>To </u><u>Find</u>;</h3>
- The value of a² – 4b + 2c
Now, Evaluate
a² – 4b + 2c
(1)² – 4(-3) + 2(2)
1 + 12 + 4 = 17
Thus, The value is 17
