Answer:
g(- 4) = - 32
Step-by-step explanation:
substitute x = 4 , g(4) = - 4 into g(x)
4a + b = - 4 → (1)
substitute x = 6 , g(6) = 3 into g(x)
6a + b = 3 → (2)
subtract (1) from (2) term by term to eliminate b
2a + 0 = 3 - (- 4)
2a = 3 + 4 = 7 ( divide both sides by 2 )
a = 3.5
substitute a = 3.5 into (1) and solve for b
4(3.5) + b = - 4
14 + b = - 4 ( subtract 14 from both sides )
b = - 18
Then
g(x) = 3.5x - 18 , so
g(- 4) = 3.5(- 4) - 18 = - 14 - 18 = - 32
The percentage of men is more than 72 inches tall will be 0.15866.
<h3>What is the z-score?</h3>
The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.
The z-score is given as
z = (x – μ) / σ
Where μ is the mean, σ is the standard deviation, and x is the sample.
Suppose the mean height for men is 70 inches, with a standard deviation of 2 inches.
Then the percentage of men are more than 72 inches tall will be
z = (72 – 70) / 2
z = 1
The percentage of men is more than 72 inches tall will be
P(x > 72) = P(z > 1)
P(x > 72) = 1 – P(x < 72)
P(x > 72) = 1 – 0.84134
P(x > 72) = 0.15866
Thun, the percentage of men are more than 72 inches tall will be 0.15866.

This simply means that the equation of the line is a horizontal line at the appropriate y value, in this case 49.
F(X) = 49
Y = 49.
Draw a horizontal line on the y axis at the 49th number, basically, the X coordinates of all other points, would vary, but the y coordinate is the same for all of them. As the graph continues.
Domain is all real number
Range is not, it would be 49 only.
