algebra
a function is a one-to-one and many-to one relation
Algebra 1 is a class/course that is on a higher level than Algebra.
If the function of the variable x, is f(x) then the roots are all the values of x (in the relevant domain) for which f(x) = 0.
One use of Boolean algebra is to minimize any function or logic gate.
Pre-algebra preps you for algebra.2nd answer:Pre-AP-algebra is the same as Algebra I. Both are way harder than pre- algebra.
Function
+ is the symbol
The function in algebra of ordered pairs is function notation. For example, it would be written out like: f(x)=3x/4 if you wanted to know three fourths of a number.
foundations algebra is probably pre algebra, which is before algebra, so no.
pre-algebra
yes
