Tricia completed the square of the quadratic function f(x)=x^2+14x+2 and determined the coordinates of the minimum value are (-7

eduard

To complete the square you halve the coefficient of the x term and square it. Half of 14 is 7 and 7² is 49. So we add 49 and subtract 49, which means we are not changing the value of the quadratic. So we have x²+14x+49-49+2. This can be written: (x²+14x+49)-49+2, which is (x+7)²-47, which is answer a.

A function is a rule that assigns each value of the independent variable to exactly one value of the dependent variable. True or

vesna_86 [32]

The answer is true
Let's imagine that we have the following function function:
 $y = x ^ 2 
$
We have to:
Independent variable: x
Dependent variable: y
For x = -1:
 $y = (- 1) ^ 2 = 1 
$
 For x = 1:
 $y = (1) ^ 2 = 1 
$
 We observe that the independent variable can only obtain one result.

True
