Answer:
-3 < x < -2
Step-by-step explanation:
Here, we want the interval in which g is increasing
The interval are the point in which we have an upward curve
From the given graph, we can see an upward curve at -3 < x < -2
And that is our answer
1.085 litres is the juice left at the end of the day
To get f(h(x)), we simply plug h(x) into the x value(s) of f(x), resulting in
2(x²+1)-1=2x²+2-1=2x²+1
For g(f(x)), we plug f(x) into the x value(s) of g(x), resulting in
3(2x-1)=6x-3
There is 2 red fives in a deck ( Hearts and Diamonds) and 2 red fours, for a total of 4 possible cards.
This would give a probability of 4/52, which reduces to a 1/13 probability.
