Question

Select the correct answer from each drop-down menu.

Consider the equations below.


Use the equations to complete the following statements.

Equation __ reveals its extreme value without needing to be altered. The extreme value of this equation has a ____ at the point (__,__ ).

Answer 1

its actually choice b maximum and 2,5

Explanation:

plato or edmentum

Answer 2

All of given options contain quadratic functions. One way to determine the extreme value is squaring the expression with variable x.

Option B contain the expression where you can see perfect square. Thus, equation
`\bf{y=-(x-2)^2+5}` (choice B) reveals its extreme value without needing to be altered.

To determine the extreme value of this equation, you should substitute x=2 (x-value that makes expression in brackets equal to zero) into the function notation:

`y=-(2-2)^2+5=5.`

The extreme value of this equation has a minimum at the point (2,5).
