Answer:

The range is all real numbers.

Step-by-step explanation:

Range is simply all the y-values you could have when you substitute any given x-value.

Domain refers to all x-values that can be substituted into a function.

In the case of linear functions with a gradient, which are line equations, both the the domain and range are always "all real numbers" because any x-value can be substituted into the function and any y-value can be generated.

What is x^4-10x^2+9 simplified

Zanzabum

$\bf \textit{difference of squares}
\\ \quad \\
(a-b)(a+b) = a^2-b^2\qquad \qquad 
a^2-b^2 = (a-b)(a+b)\\\\
-------------------------------\\\\
%x^4-10x^2+9 
x^4-10x^2+9\implies (x^2)^2-10x^2+9\implies (x^2-9)(x^2-1)
\\\\\\
\underline{(x^2-3^2)}(x^2-1^2)\implies \underline{(x-3)(x+3)}(x-1)(x+1)$

$\bf \textit{keep in mind that }1=1^2=1^3=1^5=1^{10}=1^{1000000}$
