What is the range of #y = 2x-2#?

Answer 1

Abigail Allen

Range of #y = (-oo,+oo)#

#y = 2x-2#

#y# is a straight line defined #forall x in RR#

#y# has no upper or lower bounds.

Hence, the range of #y = (-oo,+oo)#

This can be inferred from the graph of #y# below.

graph{2x-2[-16.24, 16.23, -16.47, 32.48]}

To find the range of the function ( y = 2x - 2 ), consider that it represents a linear equation.

The range of a linear function in the form ( y = mx + b ) (where ( m ) is the slope and ( b ) is the y-intercept) is all real numbers.

Therefore, the range of ( y = 2x - 2 ) is all real numbers, or ( (-\infty, \infty) ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
