- g(-1) = -1
- g(1) = -3/2
- g(5) = -7/2
======================================
Explanation:
The piecewise function g(x) is defined based on what the input is.
- If the input x is less than -2, then g(x) = 2
- Or if
then g(x) = -(x-1)^2+3 - Or if
then g(x) = (-1/2)x-1
---------------
In the case of g(-1), we have x = -1 which makes
true.
So we'll use the second piece
g(x) = -(x-1)^2+3
g(-1) = -(-1-1)^2+3
g(-1) = -(-2)^2+3
g(-1) = -4+3
g(-1) = -1
----------------
For g(1), we have x = 1 which makes
true
We'll use the third piece
g(x) = (-1/2)x-1
g(1) = (-1/2)*1 - 1
g(1) = -1/2 - 1
g(1) = -1/2 - 2/2
g(1) = -3/2
-----------------
For g(5), we have x = 5 which makes
true
g(x) = (-1/2)x-1
g(5) = (-1/2)*5-1
g(5) = -5/2 - 1
g(5) = -5/2 - 2/2
g(5) = -7/2
Answer:
7.2 miles per hour
Step-by-step explanation:
The answer is B! Because 5 x 5 x 5 x 5 = 625
Because it is BELOW sea level after 10 minutes, it straight away cannot be A) or B), because ascended means going up, so it has to be either C) or D).
I believe the answer is C), as the answer for D) would be -40 meters per minute, but it's still 40. I'm not sure though, so it's either C) or D).
Y = -1/3x + b
then plug it in
-4 = (-1/3 x 6) + b. (6 times -1 divided by 3)
-4 = -2 + b. (move -2 to other side)
b = -2. (now put em all together)
y = -1/3x -2
