Question

[Algebra 2 / 24 POINTS] Increasing/decreasing functions. Picture included.

Answer 1

A function f(x) is said to be increasing and Decreasing, if for any two x values , $x_{1} ,\text{and},x_{2}$

If,

$x_{1} >x_{2}\\\\ \text{then}\\\\ f(x_{1}) >f(x_{2})$

And ,said to be decreasing , if

$x_{1} >x_{2}\\\\ \text{then}\\\\ f(x_{1})$

And ,Constant function , if it is Neither increasing function nor Decreasing function.

→It is given that, the function is an even function.So, graph will be Symmetrical in first and Second Quadrant.

→If you will look in first Quadrant, in the Interval (7,9) the even function is Constant.

So, the function will be, Constant, in the interval , -9<x<-7.

Option C

2.⇒The function is increasing in the interval

    -7<x<-3

Option B: -7 < x < -3

3.⇒Point (5,8) lies on the graph of the function.

So, Point (-5,8) will also lie on the graph of the function.

Option A: (-5,8)
