1. when x⇒∞, y=∞ and when x⇒-∞, y=-∞
So, we have a odd degree polynomial (x³ or or even
).
The leading coefficient is negative its end behavior matches x³ which has a positive leading coefficient.
2. when x⇒∞, y=∞ and when x⇒-∞, y=∞
So, we have a even degree polynomial (x² or or even
).
And because it matches these parent functions listed above (they all have positive leading coefficients), the leading coefficient is again positive.
answers:
1. odd and positive
2. even and positive
Answer:
Dimensions of rectangle : Width = , Length =
Area of Rectangle =
Step-by-step explanation:
A rectangle constructed with its base on the x-axis and two of its vertices on the parabola
Supposing coordinates of upper right vertex of rectangle are P =
Due to parabola symmetry, width of rectangle is twice the horizontal (X) axis distance between Y axis & point P.
Width of rectangle :
Length of rectangle :
Area of Rectangle = Length x Width
() (
)
=
Answer:
Step-by-step explanation:
1. You have the following information given in the problem above:
- y represents total earnings in dollars .
- x represents hours worked.
2. Keeping on mind that the expression must model the wages of someone who makes $11.50 in an hour, this amount of money per hour must multiply the hours worked, which is represented by x.
3. Therefore, you can write the following equation:
