Definition of vertical line test

Mathematics
1 answer:
Serhud [2]3 years ago
4 0

the vertical line test is a graphical way to determine whether or not the graph is a function of x

if you can draw a vertical line on a graph and cross the graph at least 2 times, the graph is not a function

a function will have 1 y value for every x value, therefore, if we can draw a vertical line (x=c, a constant) that intersects the curve at more than 1 point, then that point where it intersects at more than 1 point is where 1 value of x coresponds to more than 1 value of y and is therefore not a function

What is the orthocenter of the triangle with two altitudes given by the lines x=-1 and y=x+1

The answers are as follows.

a. 9x

In order to get this, you need to reevaluate 64 as a base of 4. Since 64 is equal to 4^3, we can rewrite the right side as

64^3x = (4^3)^3x = 4^9x

Which gives you the first answer.

b. 10

Similar to the first problem, we need to express 16 as a base of 2. 2^4 is equal to 16, so we use that in it's place and simplify.

16^5/2 = (2^4)^5/2 = 2^20/2 = 2^10

c. Sqrt(7.31)

This one is more simple. Raising something to a 1/2 power (.5) is the same as taking the square root.
