Answer:
option C and option D the function f(x) is increasing.
Step-by-step explanation:
" A graph is said to be increasing in an interval if it's value keeps on increasing in that particular interval ".
By looking at the graph attached in the question we could clearly see that the function f(x) is increasing in the interval (-1.6,0] and [0,0.8).
and in all the rest options asked in the question the function f(x) is decreasing.
Hence, for option C and option D the function f(x) is increasing.
Answer: B
because of the reason given. (smaller numbers are father left and larger numbers are father right on the number line).

Answer:
Step-by-step explanation:
Apply exponent rule :
Possible values for x and y:
You did not include the given line to which your line is parallel to.
Nevertheless, I can explain you how to solve this problem and which the possible solutions are.
1) x-intercept = - 3 = y = 0
The only two equations that include the point (-3,0) are y = x + 3 and y = - x - 3 (you likely forgot to place the negative signs).
You can prove that in this way:
a) y = x + 3
y = 0 => x + 3 = 0 => x = - 3
b) y = - x - 3
y = 0 => - x - 3 = 0 => x = - 3
Then, so far you have two options: y = x + 3 and y = - x - 3.
2) The slope of y = x + 3 is 1 and the slope of y = - x - 3 = - 1 (the coefficient of the x).
3) You know that line whose equation you are determining is parallel to the given line. That means that their slope are the same. So, your next step is to determine the slope of the given line. It shall be either 1 or - 1. Once you have the slope, you will know whether the solution is y = x + 3 or y = - x - 3.
