(f - g)(x) = f(x) - g(x)
(f - g)(x) = ( f(x) ) - ( g(x) )
(f - g)(x) = (4x^2 - 6) - ( x^2 - 4x - 8)
(f - g)(x) = 4x^2 - 6 - x^2 + 4x + 8
(f - g)(x) = (4x^2-x^2) + 4x + (-6+8)
(f - g)(x) = 3x^2 + 4x + 2
<h3>Answer: Choice D</h3>
Step-by-step explanation:
The formulae for median is
N=£f/2 that is the sum of frequency divide by two
Median =Nth term + (N + 1)th term divide by two
first of all do the cumulative frequency which is
2+0=2
2+8=10
10+4=14
14+10=24
24+6=30
therefore N=£f/2
N=30/2
=15
when you use the formulae
it will be 15+(15+1)/2
then check the cumulative frequency the value close to the range of 15 and 16 which is 14
then you trace 14 back to the conceded goals
which is 2
then you add 2+2 and divide by two
which is= 2
therefore the median is 2
Mean
formulae
mean=conceded goals multiply by the frequency/sum of frequency
0*2=0.
1*8=8
2*4=8
3*10=30
4*6=24
total is 70
sum of frequency is 10
according to the formulae 70/10=7
therefore the mean is 7
Answer:
using the formula is 87°F but without it is near 140°F

Rhombus or diamond I think. I hope that this helps!
