Welcome to Precalc!
A New Symbol and Use - Hi,
-
- You already know some symbols, today you will learn the inverse and composite function.
- I calc I, you will learn the derivative and antiderivative symbols.:
- x -- a number, a
variable a domain value
- f(x) -- a
function of x -- the range values
- - x -- the
opposite of x, its or additive inverse
- 1/x, or x-1 -- the
reciprocal of x, its multiplicative inverse
- f(g(x)) -- a function of a function, a
composite function
- f-1 - the
inverse,
the of function f(x) -- the function, if it exists,
that "undoes" f(x)
- dy/dx, or f'(x), or f(1) -- the
derivative - the instantaneous
rate of change of f(x), its slope function
- f(-1), or F(x) - the
antiderivative - cumulative function
- You know the blue symbols/material.
- We do the red symbols/material today.
- Forget the green
material/symbols until next semester.
- If needed, contact me through the pink box on www.mathnstuff.com/math/math.htm
- or with the phone number on your class CANVAS home page.
- Stay safe, A2
