Number line with closed dots on negative 1.5 and 1 with shading in between.
Answer:
The graph would need to go through the coordinates (0, 1) and (8, 1) instead of (1, 0) and (1, 8); we would plot the population on the y (dependent) axis and time on the x (independent) axis.
Answer:
f( g(x)) = 18 *x*x + 6
g( f(x)) = 6xx + 18
Step-by-step explanation:
we want f (g(x)) and g( f(x))
f = 2xx + 6 g = 3x
f( g(x)) = 2 *(3x)*(3x) + 6 = 18 *x*x + 6
g( f(x)) = 3*(2 xx + 6 ) = 6xx + 18
1. 6=a/4+2
6-2=a/4
4=a/4
4(4)=a
a=16
2. -6+x/4=-5
x/4=-5+6
x/4=1
x=4
3. 9x-7=-7
9x=-7+7
9x=0
x=0
4. 0=4+n/5
-4=n/5
-4(5)=n
n=-20
5. -4=r/20-5
-4+5=r/20
1=r/20
r=20
6. -1=(5+x)/6
-1(6)=5+x
-6=5+x
x=-11
8. 2(n+5)=-2
n+5=-1
n=-6
9. -9x+1=-80
-9x=-81
x=9
10. -6=n/2-10
4=n/2
8=n
-2(x+9)-6=-24
-2x-18-6=-24
2x=0
x=0
2(x+9)-6=-24
2x+18-6=-24
2x=-36
x=-18
