For each function, do the following: a) state the name of the function, b) identify the independent and dependent variable, c) i
dentify the rule that assigns exactly one output to the very input, and d) evaluate the function for the given input value.
1 answer:
<h3>
Answer</h3>
Given in the question the equation
y = x² - 2x + 6
Name
a quadratic polynomial or a polynomial of degree 2
Ind. var
An input value of function is the independent value = x
Dep. var
The output value of function is the dependent value, as it depends on the value of the input = y
Rule
a function is a rule that assigns to each input exactly one output.
Evaluation
when x = -3
y = (-3)² - 2(-3) + 6
= 21

Hello,
x² + 5x + 6 = 0
