Answer:
f(-2) = 0
f(0) = -4
f(4) = 12
Step-by-step explanation:
Given the function f(x) = x^2 - 4, we must plug in the values substituting x for each of the answers.
f(-2) = (-2)^2 - 4
-2 times itself is a positive 4, therefore:
f(-2) = 4 - 4
f(-2) = 0
We do the same for each answer.
f(0) = (0)^2 - 4
f(0) = -4
f(4) = (4)^2 - 4
f(4) = 16 - 4
f(4) = 12
In statistics, the 68–95–99.7 rule, also known as the empirical rule, is a shorthand used to remember the percentage of values that lie within a band around the mean in a normal distribution with a width of two, four and six standard deviations, respectively; more accurately, 68.27%, 95.45% and 99.73% of the values lie .
The slope of the line is -1. Have an awesome day and if you have anymore math questions don't be afraid to pm me/post on my message board :)
Answer:
Step 4
Step-by-step explanation:
Step 4 is incorrect because when you add the number from the right side, -34, you make it a positive coming to the left side, -17, which stays the same. so 34+-17, will give you 17.
This will make Step 4: Addition property of equality: -17x=40
Therefore Step 5 is also incorrect, and should look like: Step 5: Division Property of Equality: x= 40/-17
Answer:
The parallel line is y = 1/7 x - 1
hope this helps!
