Answer:
Step-by-step explanation:
We have a piesewise function composed of three pieces. two line segments and one point.
The first line cuts at point (0,0) and ends at point (3, -1)
If we use these two points we can find the equation of the line.
The slope m is:
So the equation is:
As the line cuts in (0,0) then 
and the equation is:
The equation of the second line is:
Now we can find f(x) (although it is not necessary to find the equation of f(x) because we have its graph)
if 
; 
if 
; 
if 
.
The limit of f(x) when x tends to 3 from the left 
is the limit of the function when x approaches 3 from the left. If x approaches 3 from the left then 
. If then f(x) is given by the line . Then the limit is -1 as seen in the graph
You could either:
a) Use the Pythagorean Theorem
b) Use Sine/Cosine/Tangent Inverse to find one of the angles, and then use that angle to find x.
4a²b⁴ - 25x⁶y⁴
(2ab²)² - (5x³y²)²
= (2ab² + 5x³y²)(<span>2ab² - 5x³y²) By difference of two squares</span>

Answer:
, D
Step-by-step explanation:
3 if x is greater than or equal to 1 is nothing. That leaves us with 
if x<1. If you substitute in 1 for x, you get 3, but of course that isn't possible, so the range is , which is D.
