Answer: d/dx (f(x)) = 2x + 5
Ok done. Thank to me :>
The room has 16*12= 192 feet
192:2=96 tiles need Mrs Ellis
96*0,84 $=80,64 $ is the cost
Answer:
A. Both functions are positive and decreasing on the interval.
Step-by-step explanation:
The table shows that f(x) decreases when x increases in the interval (0,3).
All the values of f(x) are positive in the interval (0,3).
For the exponential function that passes through the points (0, 27) and (3, 0), we also see that f(x) is decreasing when x increases: when x goes from 0 to 3, f(x) goes from 27 to 0.
Also all the values of f(x) are positive in the interval.
Then, both functions are positive and dereasing in the interval.
