Is this function linear or nonlinear? y=1x

Linear means that the exponent is 1
y=1x^1
yes
true

A linear function is in the form y = mx + b or f(x) = mx + b, where m is the slope or rate of change and b is the y-intercept or where the graph of the line crosses the y axis.  This function is linear, this is because y = 1x is in the form y = mx, there the + b is just + 0 since there is nothing adding into it.

Answerthe simplified expression isexplanationthe given expression is,let us deal with the bracket first.the two negatives in the parenthesis will become positive.the expression now becomes,we now expand the parenthesis to get,we group like terms to obtain,this simplifies to,
