Hey!

-------------------------------------------------

In a function <u>ONE input-value can be assigned to only ONE output-value.</u>

We can use the <u>vertical line test</u> to see whether each graph is a function or not.

-------------------------------------------------

Graph 1, 5, and 6 are functions. When we draw a line vertically we can see that the line only passes through 1 point on the graph.

Graph 2, 3, and 4 are NOT functions. When we draw a line vertically we can see that the line passes through more then 1 point on the graph.

-------------------------------------------------

Hope This Helped! Good Luck!

A set of data has a normal distribution with a mean of 29 and a standard deviation of 4. Find the percent of data within each in

Nikolay [14]

Let x be the population distribution.
p(25 ≤ x ≤ 33) = p((25 - 29)/4 ≤ z ≤ (33 - 29)/4) = p(-1 ≤ z ≤ 1) = p(z ≤ 1) - p(z ≤ -1) = p(z ≤ 1) - [1 - p(z ≤ 1)] = 2p(z ≤ 1) - 1 = 2(0.84134) - 1 = 0.68268 = 68%

p(21 ≤ x ≤ 25) = p((21 - 29)/4 ≤ z ≤ (25 - 29)/4) = p(-2 ≤ z ≤ -1) = p(z ≤ -1) - p(z ≤ -2) = [1 - p(z ≤ 1)] - [1 - p(z ≤ 2)] = p(z ≤ 2) - p(z ≤ 1) = 0.97725 - 0.84134 = 0.13591 = 13.5%
