Answer:
x^2-x+5
Step-by-step explanation:
(f-g)(x)=f(x)-g(x)
= (x^2 + 3) - (x - 2) (Don’t forget the -1 multiplies to the x AND -2
= x^2 + 3 - x + 2
=x^2-x+5
Answer: 
Step-by-step explanation:
Given : Sample size : n= 33
Critical value for significance level of
: 
Sample mean : 
Standard deviation : 
We assume that this is a normal distribution.
Margin of error : 
i.e. 
Hence, the margin of error is 
Answer:
Step-by-step explanation:
Hi there!

f(x) = -2x - 3
Plug in 0 for "x" to solve for f(0):
f(0) = -2(0) - 3
f(0) = -3
Since the question is asking you to evaluate f(0) - 7, simply subtract:
-3 - 7 = -10.
