-- It'll be a lot easier if you clean up the function first.
You're not changing the function. You're just making it
easier to read and work on without mistakes.
Notice that 3x3=9 , so the function is f(x) = 9 - 4x + 5
Combine like terms, and the function is f(x) = 14 - 4x .
Much easier to work with.
-- Now, when somebody tells you to evaluate the function <em>for some number</em>,
just take their number, write it in place of 'x',and see what you've got.
Example:
f(x) = 14 - 4x
Evaluate f(x) for x = 3.
-- Write 3 in place of 'x' in the function: f(3) = 14 - 4(3)
-- 4(3) = 12 . So the function is f(3) = 14 - 12
-- Finish up the subtraction : <em> f(3) = 2</em>
You just evaluated f(x) for x=3.
Nice job !
Answer:
C.
Another way to write the added percent of something is by putting a 1 to indicate the aditional.
Answer:
9x2-y2 + 8xy -1
Step-by-step explanation:
9x2 -1 - y2 +8xy
9x2-y2 + 8xy -1
Answer:
Yes
Step-by-step explanation:
It is A
Theoretical probably is what you would expect to happen.
Example, flipping a coin has a 50% chance of landing on heads, so if you flipped a coin 100 times, theoretically the coin would land on heads 50 times ( 50%).
Experimental probablity is what actually happens. Using the coin example, flipping the coin 100 times, it could actually land on heads 100 times or any number of times from 0 to 100.
