Answer:
50
Step-by-step explanation:
Fastest method for calculating 34 is 68 percent of what number. Assume the unknown value is 'Y' 34 = 68% x Y. 34 = 68 / 100 x Y Multiplying both sides by 100 and dividing both sides of the equation by 68 we will arrive at: Y = 3 x 100 / 68. Y = 50%. Answer: 34 is 68 percent of 50

The graph of the step function
Before plotting the graph, it should be noted that:
and
use closed circle at its end
and
use open circle at its end
So, we have:
![f(x) = -1,\ \ \ \ x < -1](https://tex.z-dn.net/?f=f%28x%29%20%3D%20-1%2C%5C%20%5C%20%5C%20%5C%20x%20%3C%20-1)
The line stops at -1 with an open circle
![f(x) = 0,\ \ \ \ -1 \le x \le 1](https://tex.z-dn.net/?f=f%28x%29%20%3D%200%2C%5C%20%5C%20%5C%20%5C%20-1%20%5Cle%20x%20%5Cle%201)
The line starts at - 1 and stops at -1 with a closed circle at both ends
![f(x) = 1,\ \ \ \ x > 1](https://tex.z-dn.net/?f=f%28x%29%20%3D%201%2C%5C%20%5C%20%5C%20%5C%20x%20%3E%201)
The line starts at 1 with an open circle
The options are not complete, so I will plot the graph myself.
