Answer: D) The y intercept is (0,1)</h3>
This can be confirmed by plugging x = 0 into the function to find that...
y = (1/2)^x
y = (1/2)^0
y = 1
Recall that any nonzero value to the 0th power leads to 1. So we can say x^0 = 1 as long as x is not zero.

Extra info (optional section):
- We can rule out choice A because negative x values work in the domain. For instance, if x = -1, then it leads to y = (1/2)^x = (1/2)^(-1) = 2. The negative exponent will apply the reciprocal operation to the base fraction.
- Choice B can also be ruled out because the range is y > 0. Or you could note that it is possible to get positive y values smaller than 1/2. Try x = 2 and you'll see it leads to y = 1/4 which is not greater than 1/2.
- Choice C is false as well. The function f(x) = (1/2)^x is decreasing throughout the domain. A graph visually would show this due to it going downhill when moving from left to right. A table of values is a non-visual way to see we have a decreasing function. The table would show that y decreases when x increases.

Answer = x^15
Because if indices are in brackets you just multiply them together ie 3 x 5
Answer:
p(x=0)=0.000008
p(x=1)=0.00176
p(x=2)=0.0576
P(x=3)=0.941192
Step-by-step explanation:
The probability of successfully classifying any given part is 0.98. There are 3 parts in total and the classifications are independent. The random variable is the number correctly classified parts out of the total 3.
{0,1,2,3,}
