to solve on a graphing calculator, go to MATH button. then press the right key once, so that you've highlighted NUM. pick choice number 1, which is abs(. plug in the equation so that it'll look like this abs(2X-4) and press enter and there yougo!
To do this by hand, use the formula f(x)=|gx|
A piecewise function should look as follows:
f(x)={(gx) if g>0
-(gx) if g<0

How are piecewise functions related to step functions and absolute value functions?
A piecewise function is a function defined by two or more equations. A step functions is a piecewise function defined by a constant value over each part of its domain. You can write absolute value functions and step functions as piecewise functions so they're easier to graph.
Different types of functions in maths?
Piecewise, linear, exponential, quadratic, Onto, cubic, polynomial and absolute value.
What do the absolute value of a function do to the graph of that function?
The absolute value of a function changes the original function by ensuring that any negative y values will in essence be positive. For instance, the function y = absolute value (x) will yield the value +1 when x equals -1. Graphically, this function will look like a "V".
What do integers and absolute value have to do with each other?
The absolute value of an integer is the value of the integer without regard to its sign. The absolute value need not be an integer.
What is the parent function of absolute value?
apex what is the range of the absolute... answer is nonnegative real num...
The greatest integer function and absolute value function are both examples of functions that can be defined?

Express without absolute value symbols f of x equals absolute value x plus absolute value x-2?
In order to write f(x) = |x| + |x-2| without the absolute value signs, it it necessary to write it as a piecewise function.We must define f as follows:f(x) = -2x + 2, if x < 0f(x) = 2, if 0
What is a function whose rule contains absolute value expressions?

Which function has a graph that is increasing only?
Absolute Value function
How do you graph the function of the absolute value of x?
I
Is absolute value a one to one function?
No.
What is the corner point of a graph of an absolute value equation?
It is sometimes the point where the value inside the absolute function is zero.
