CAN SOMEONE PLEASE HELP ME WITH MY PRE CALCULUS? THANK YOU SM

Step-by-step explanation:

Apply Rational Root Thereom:

If we have a polynomial, P(x), the possible roots of the polynomial are the factors of the constant divided by the factors of the leading coeffceint.

Our constant is 10 and our leading coefficient is 2 so our possible factors are (the factors are positive and negative).

10:1,2,5,10

2:1,2

So our possible roots are

Remeber to include the plus and minus sign.

According to the rational root theorem, if a polynomial

has any rational roots, they take the form of ± (some divisor of , the constant term) divided by (some divisor of , the coefficient of the leading term).

In this case, we have and , which have divisors

• 2: 1, 2

• 10: 1, 2, 5, 10

Then the possible candidates for rational roots are

±1/1 = ±1

±2/1 = ±2

±5/1 = ±5

±10/1 = ±10

±1/2

±2/2 = ±1 (already accounted for)

±5/2

±10/2 = ±5 (already accounted for)

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
