6. describe the end behavior and determine
whether the graph represents an
odd-degree or an even-degree polynomial function. then state the number of real 0s

7. geometry recall the formula for finding the area of a rectangle define a
variable for the width and set up an equation to find the dimensions of a rectangle with an area of 144 square inches given the length is 10 inches longer than the width

6. an odd-degree polynomial function.

    f(x)⇒-∞ as x⇒-∞ and f(x)⇒∞ as x⇒∞

7. Length =x+10=8+10=18 inches

   Width=x=8 inches

Step by step explanation;

6. The graph represent an odd-degree polynomial function.

The graph enters the graphing box from the bottom and goes up leaving through the top of the graphing box.This is a positive polynomial whose limiting behavior is given by;

f(x)⇒-∞ as x⇒-∞ and f(x)⇒∞ as x⇒∞

7.

The area of a rectangle is given by l×w, where l is length and w is the width

Let=w=x  , l=x+10  and A=144 in² then;

l×w=144

(x+10) × x = 144

x²+10x =144complete squares on both sides

x²+10x+25=144+25

x²+10x+25=144+25factorize

(x+5)²=169square root the right-hand side

x+5= ±√169

x+5=±13.

x+5=13⇒⇒⇒x=8

x+5=-13⇒⇒⇒x= --18

x=8 inchesvalue of width should be positive

Length =x+10=8+10=18 inches

Width=x=8 inches

hope this !
