What is the maximum number of x-intercepts for a 6th-degree function

find horizontal and vertical intercept of f(x)= -2|x+1|+6 and graphing the function

A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 8 inches.Write a list of six ordered pairs to show the height of the candle in inches (y) as a function of time in hours )x) from the first hour after it started burning. For example, the point (0,8) would represent a height of 8 inches after 0 hours. Explain how you obtained the ordered pairs Is this relation a function? Justify your answer using the list ordered pairs made in the first part. If the rate at which the candle burned was 0.4 inches per hour instead of 0.5 inches per hour, would the relation be a function and explain the answer using input and output values.

The closing stock price of a company for the years 2009 to 2023 was approximated using the function f(x) = - 0. 32x2 + 12x - 48, where X = 9 corresponds to the start of the year 2009. What was the company's stock price at the start of 2023?
