Answer:
range of f is [0,3]
Step-by-step explanation:
The "square root" symbol, , is a function. As a result, it only has a single output because functions must only have a single output for each input.
Thinking about it graphically, if the square root function did give both a positive and a negative result, the function "f" would not pass the vertical line test and it would not be a function.
When solving an equation like , to solve, we must apply the square root property. The square root property says that to find both solutions, one must look at both the positive and the negative of the square root. So, to solve:
Apply square root property...
or
or
In this case, because the square root function itself only outputs non-negative results (so, including zero, as you already identified), the range will only be [0,3].
It's C)
the graph is decrasing, so the variable rate is negative (-2/3)
the rest was quite easy, you just take a look at where the graph cuts the y-axis and determine the rest from the rate of going up or down (increase/decrease)
Answer:
p - 3
Step-by-step explanation:
"fewer than" means subtract from, in this case 3, from an unknown number represented by p

Answer:
Peer reviewed journal articles are also an important source of information for literature reviews in research proposals and need to be included.
Step-by-step explanation:
Internet provides vast amount of information, but the information coming from world wide web may not be verifiable. Peer reviewed sources are reliable, therefore this kind of sources also need to be added in researches.
