<span>You can get those ordered pairs subtracting 9-0.5, then that result minus 0.5 because from the rate the candle reduces its height 0.5inches per each hour.Part B: Is this relation a function? Yes, because each value of x has a single result or output in “y” (image)Part C: Yes, only difference is the time, the candle reduces its height 0.45 inches per each hour, examples of ordered pairs: (0,9) (1,8.55) (2,8.1)</span>
Again, "It is a Function" as y-coordinate is not repeating for different y-'s. We've just decreased the y's, it doesn't affect x-coordinate, so the nature of our function won't change
Let the leading term of the polynomial, f(x), be axⁿ.
Examine the possibilities. n a x -> - ∞ x -> +∞ ------- ---- ----------- ------------ even a>0 f -> +∞ f -> +∞ Not true even a<0 f-> - ∞ f-> -∞ True odd a>0 f-> -∞ f-> +∞ Not true odd a<0 f-> +∞ f-> -∞ Not true
Answer: (a) the degree of the polynomial is even, and (b) the coefficient of the leading term is negative.
X would have to equal 6. To work it out, you subtract 4 from each side to cancel out the 4. -x = -6. You have to make -x just x so you × each side by -1. You get x = 6.
