Step-by-step explanation:
the second and the 6th options keep the same graph but shift it to the left.
the other options :
the first option changes the graph (the factor -2 stretched and flips the graph).
the third and the 5th options shift the graph up and down. but not to the left.
the 4th option shifts it to the right.
when you add a constant inside the x terms, you shift to the left.
when you subtract a constant inside the x terms, you shift to the right.
e.g. when having f(x+2), then everything, that should happen at x+2 happens already at x. 2 units earlier, and therefore a shift to the left.
in the other direction, f(x-2) makes everything that should have happened at x-2 happen finally at x. so, everything shifts 2 units to the right.
Answer:
Step-by-step explanation:
Lets do this week by week
beginning pressure 45 pounds
end of week 1
45 *.06 = 2.7
45 - 2.7 = 42.3
end of week 2
42.3 * .06 = 2.538
42.3 - 2.538 = 39.762
end of week 3
39.762 *.06 = 2.38
39.762 - 2.38 = 37.37
end of week 4
37.37* .06 = 2.2425
37.37628 - 2.2425= 35.12
end of week 5
35.12 * .06 = 2.107
35.12 - 2.107 = 33.012
end of week 6
33.012* .06 = 1.98
33.012 - 1.98 =31.03
Here is the fast way to get to this answer.
do 1-.06 = .94
then do
45(.94)(.94)(.94)(.94)(.94)(.94) = 31.04
in slope intercept form :
y = 2x - 19
( I think )
The graph intersect the y axis in (0,1)
⇒ if x=0 ⇒ y=1
y+2= - 3/2(x-2)
if x=0 ⇒ y+2= - 3/2*(-2)=3 ⇒ y=1
when y=0 ⇒x<1
2= - 3/2(x-2)
2= -3/2x+3
2-3=-3/2x
x=-1:(-3/2)=2/3 <1
⇒ The answer is y+2= - 3/2(x-2)
