Difference means - so 4-(-8)
which also the same as 4+8 so ur answer is 12
The answer is A:
Because the only difference between the rest of the answer choices are the lower and upper quartiles, that is all you need to find. In order to do so you find the median for the first half (lower quartile) and then find the median for the second half. In this case it is 29 (Q1) and 58 (Q2)
Answer:
g(f(x)= x^3+3x^2+3x+1
Step-by-step explanation:
the statement tell us:
f(x) = x + 1
g(x) = x^3
so we have:
g(f(x)=(x + 1)^3
g(f(x)= x^3+3x^2+3x+1
6x^2+14x+4
First factor out all numerical factors (=2 in this case)
2(3x^2+7x+2)
look for m,n such that m*n=3*2, m+n=7 => m=6, n=1
2(3x^2+6x + 1x+2)
Factor 3x^2+6x into 3x(x+2)
2( 3x(x+2)+1(x+2) )
factor out common factor (x+2)
2(x+2)(3x+1)
=>
6x^2+14x+4=2(x+2)(3x+1)
