restrict the domains of quadratic functions and absolute value functions, because these functions are
functions. For instance, the quadratic function f(x) = x^2 pairs both −2 and 2 with 4, and the absolute value function f(x) = |x| pairs both −2 and 2 with 2.
Linear functions (excluding constant functions) and exponential functions are
functions, so their domains
to be restricted.
_________________
An absolute value function, without domain restriction, has an inverse that is NOT a function.
In order to guarantee that the inverse must also be a function, we need to restrict the domain of the absolute value function to make it a one-to-one function.
Answer:I write the answer in the paper
Step-by-step explanation:
-4²
Any number repeatedly multiplied by itself has an exponent. so (-4)(-4) has an exponent of 2 while (-4)(-4)(-4) would have an exponent of 3 and be written as -4³.
Also extra tip: Negative numbers multiplied by a negative number will always be positive.
Answer:
y = 
Step-by-step explanation:
Hello!
The graph linked above is what is known as a "Reciprocal Graph"
A reciprocal in math is a multiplicative inverse or reciprocal for a number x.
For example the reciprocal of 1/2 is:
With this in mind we know that our graph will have the function 
Shown below is the graph of
