Math Help!!! How many x-intercepts does the graph of the function have?
dalvyx [7]
It can have however many x intercepts it wants, 

<span>BUT, to be a function it must pass the vertical line test. </span>
<span>this means you have to look at the graph and see if a vertical line drawn anywhere hits the graph more than once. </span>
<span>if it hits it more than once, it is NOT a function. 
</span>
An example is a polynomial function to the infinite degree. That is 
f(x) = lim (n --> infinity) [ x^n] 
but only 1 y intercept (vertical line test remember)

The average number of points you scored in the first 9 basketball games of the season was 23. What do you need in the 10th game
Vlada [557]

Answer:

B. 10n-207

Step-by-step explanation:

Given,

The average number of points of 9 games = 23,

∵ Sum of observations = their average × number of observations

So, the total points for 9 games = 9 × 23 = 207,

Now, if the average of 10 games is n,

Then the total points for 10 games = 10n,

Hence, the number of points earned in 10th game = the total points for 10 games - the total points for 9 games

= 10n - 207

i.e. OPTION B is correct.
