Question

IF THE RANGE OF X IS 2, WHAT WOULD BE THE RANGE OF -3X+50

Answer 1

Substituing x=2 in -3x+50
-3x+50=-3(2)+50
            =-6+50
            =44
Thus the range of -3x+50 is 44

Answer 2

Concept

Given a function between x and y where x is the independent variable and y is the dependent variable, the range of the function denotes all the possible values that y can take.

Given

Range of X is 2

Find

we need to find the range of -3X+50

Solution

We have X = 2

We can find the range of -3X + 50 by substituting the values that X can take. Here, X can take only one value, that is 2, hence the range will be only one number calculated as follows

-3(2) + 50

= -6 + 50

=44

Thus, if the range of X is 2, the range of -3X + 50 will be 44.
