Answer:
You are trying to find the x-value when the y-value is 2. On the graph, the x-value is -3 when the y-value is 2. So, the x-value when f(x)=2 is -3.

The value of z-score for a score that is three standard deviations above the mean is 3.
In this question,
A z-score measures exactly how many standard deviations a data point is above or below the mean. It allows us to calculate the probability of a score occurring within our normal distribution and enables us to compare two scores that are from different normal distributions.
Let x be the score
let μ be the mean and
let σ be the standard deviations
Now, x = μ + 3σ
The formula of z-score is

⇒ 
⇒ 
⇒ 
Hence we can conclude that the value of z-score for a score that is three standard deviations above the mean is 3.

Answer:
y=3x ( the'=' sign is the proportionality sign)
Step-by-step explanation:
x = 1 , 2 , 3 , 4
y = 3 , 6 , 9 , 12
You are multiplying by 3 to get to y
1 x 3 = 3
2 x 3 = 6
3 x 3 = 9
4 x 3 = 12
