Basic Rules of Applications Short Answers Flashcards
standard approximation for Δf
Δf ≈ f’_0Δx
standard approximation for f_1
f_1 ≈ f_0 + f’_0Δx
equation for a linear approxiamtion of f
L(x) = f_0 + f’_0Δx or L(x) = f_0 + f’_0(x_1-x_0)
When is the linear approximation accurdate?
Near x_0
whats the difference between a linear approximation and an f_1 approxiatmion
x_1 is left as x
What do curves with deriation look like when you zoom in on them?
a straight line
whats the relationship between the graph of as function and the graph of one ofits linear approximations
the linear approximation is a tangent line
Intuitively what is f’(x)?
f ‘s per x
What is the value of Seconds’(Minute)?
60
Intuitively why is 20’ = 0
20 never changes. It’s a constant
Write “if one worker makes 20 widgets per hour, then 3
workers make 320 widgets” in symbolic notation.
(3𝑊(ℎ))′ =3𝑊′(ℎ)
Write “if a husband makes $60K per year and his wife
makes $50K per year then together they make
60+50K per year” in symbolic notation.
(𝐻(𝑦)+𝑊(𝑦))′ =𝐻′(𝑦)+𝑊′(𝑦)
What happens to the graph of a function when you add a number to the function?
The graph goes up.
What happens to the slope of a function when you add a number to the function?
Nothing. It’s the same slope just higher.
