This function would be
                1
f(x) = ---------------
             (x-1)^2

What do we know about this fn?  
1) it's even, because of that power "2."
2) All of the graph is above the x-axis.
3) The x-axis is the horiz. asymptote.
4) the vertical line x=1 is the vertical asymptote.
5) as you approach x = 1 from either side (from the left or from the right), the y value will increase without bound.  
6) because of this "without bound" growth, the function has no limit at x = 1.

Answer:

\lim_{x \to\ 1}\frac{1}{(x-1)^2}=\infty

vertical asymptote at x=1

Step-by-step explanation:

\lim_{x \to\ 1}\frac{1}{(x-1)^2}

First we find out limit approaches from right

\lim_{x \to\ 1^+}\frac{1}{(x-1)^2}=\infty

BEcause the denominator is a positive quantity because it has square

we find out limit approaches from right

\lim_{x \to\ 1^-}\frac{1}{(x-1)^2}=\infty

so limit is infinity

\lim_{x \to\ 1}\frac{1}{(x-1)^2}=\infty

To find out vertical asymotote , we take the denomintor and set it =0

(x-1)^2=0

Take square on both sides

(x-1) = 0

add 1 on both sides

x=1

So vertical asymptote at x=1

In the school election James ran against Ben for secretary James received 75% of the votes if 240 students voted how many votes
scoray [572]

Answer: James did not received 60 votes.

Step-by-step explanation:

Given: In a school election,

Percentage of votes received by James = 75%

Percentage of voted hadn't received by James = 100% - 75% = 25%

If 240 students voted , the number of votes hadn't received by James= 25% of 240

=\dfrac{25}{100}\times 240\\\\=\dfrac14\times240\\\\=60

Hence, James did not received 60 votes.

Can somebody help me with this question
goblinko [34]

A function is a relationship where each x-value is paired with exactly one y-value.

When looking at a graph, you want to ask yourself, "Can I find any two points on this graph that have the same x-value?"

I can see with x=8 that there would be two points on that graph with an x-value of 8, making this not a function.

People call this test "the vertical line test" because any vertical line really represents a single x-value. If any vertical line hits the graph more than once, the graph cannot be a function, because that value of x has more than one y-value.
