The x-intercept of a function is the point where it crosses the x-axis.
The x-intercept of g(x)=log(x + 4) is -3
<h3>How to determine the x-intercept</h3>We have:
f(x) = log(x)
Rewrite as:
y = log(x)
Apply the exponent rule
Set y to 0
Given that f(x) is shifted 4 units left to get g(x).
The x-intercept of g(x) is then calculated as:
Hence, the x-intercept of g(x)=log(x + 4) is -3

Answer:
The standard error for the sampling distribution is 1.323.
Step-by-step explanation:
Let <em>X</em> = scores of girls and <em>Y</em> = scores of boys.
The information provided is:
As the population standard deviations are not known, use a pooled standard deviation to estimate the standard error of the sampling distribution.
The formula of pooled standard deviation is:
Compute the standard error for the sampling distribution as follows:
Thus, the standard error for the sampling distribution is 1.323.
