Answer:
f(1)=0; f(0)= -2; f(-1)=(-4); f(2)=2
Step-by-step explanation:
For the first four questions, f(1) means that x= 1, so you need to look at the graph, find the point where x= 1, and find the corresponding y value which is 0. You do this same process for each of the rest.
For 5 and 6: when they say f(x) = some value, this is the y value. So look at the graph: when y = 4, you can see that x = 3. When y = -6, you can see that x= -2.
Answer:
0.980
Step-by-step explanation:
Use a calculator with built-in distribution functions.
Example:
normcdf(-2.05, 10000) = 0.980
A fraction that is greater then 1/2 but less then 3/4 is 5/8.
