Answer:
a) g(-2) = -2
b) g(1) = 1
c) g(x) = 1 then x = 1 or -1
d) D: {all reals}
R: {y ≤ 2}
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given is the graph bell shaped.
We have to find the variance of the data
We see that the graph looks like a normal distribution curve symmetrical about x=19
Hence mean =19
Since we know maximum area covered within 3 std deviations on either side of mean, we can calculate 6 sigma value from the graph
Extreme left x value = 14 and right = 24
Hence 6 times std dev =24-14 =10
So std deviation = 10/6 =5/3
Variance = 25/9
Answer:
the correct answer is 4, or D
Step-by-step explanation:
the fish is descending, meaning is is decreasing in sea level. if it descends 16 feet (8 x 2) then this would be represented by -320-16 which is -336, not 336
Answer:
y = -2·(1/2)^x
Step-by-step explanation:
The ratio of one table entry to the one before is ...
(-2)/(-4) = 1/2
so this is the <em>growth factor</em>.
The <em>multiplier</em> is the value of y when x=0, which is -2. So, the equation is ...
y = (multiplier)·(growth factor)^x
y = -2·(1/2)^x
_____
This can also be written using a negative exponent:
y = -2·2^(-x)
