Answer:
Step-by-step explanation:
Graph of the given piecewise function will show the three straight lines,
f(x) = 2 If 2 < x ≤ 4
x + 3 If 4 < x < 8
2x If x ≥ 8
1). f(x) = 2 will be a straight line parallel to x-axis for 2 < x ≤ 4
2). f(x) = x + 3 is a straight line with input output points in the interval 4 < x < 8
x 4 5 6 7 8
f(x) Not defined 8 9 10 Not defined
3). f(x) = 2x
x 8 9 10 11
f(x) 16 18 20 22
By using these points on a graphing calculator we can graph the piecewise function as attached.

Answer:
Step-by-step explanation:
The objective is to combine the terms to make one radical, so therefore we know that we will have to take a out of the second radical
.
If we divide 180 by 5, we will get 36, so now we have
×
can be simplied into just 6.
So now the expression becomes
Then we can further simplify by moving the into the radical to get two common terms with
.
, so we now have
So then we can combine the two radicals to get the expression to
We now see that we have two terms with a common radical, and coefficients of -1, and 48.
That allows us to simplify further to
Here, we can take out , which is
, and get the final simplied form to be
Hope this helped.
