f(x) = -2x3 + 7x
f(x) = -x3 + 7x
f(x) = 8x5 - 9x4 + 7x2
How would you write y = 2x - 3 in function notation?
y = 2x-3
f = 2x - 3
f(x) = 2x-3
How do you read f(x)?
f x
f of x
f parenthesis x
f with an x inside parenthesis
If a question asks you to find f(2), what does that mean?
Let x = 2
Let y = 2
If f(x) = 2x + 1, what would be your first step to find f(1)?
Plug a 1 in for all the x's
Set the function equal to 1
Only plug a 1 into the left side
Only plug a 1 into the right side
If f(x) = -3x - 8, find f(-1).
f(-1) = 5
f(-1) = -5
f(-1) = -12
f(-1) = -10
If I know that f(2) = 4, what is another way I can write my answer?
2,4
(2, 4)
That is the only way to write it.
If f(x) = 6x - 9, find f(4).
(4, 1)
(4, 33)
(4, 15)
(4, -7)
Find f(10) if f(x)= 10x - 100.
f(10) = 200
f(10) = 0
f(10) = -100
f(10) = -99
