Question

a) f(x)=5x-3 find the domain and range?explain in detail plz

Answer 1

This function represents a straight line when graphed therefore the domain is from (-infiniti, infiniti) The range is also (-infiniti, infiniti) There are no restriction intervals so this function is defined that way. Any value of x on the number line will define the function

Answer 2

This is a linear equation so domain={xer} (x is an element of the real numbers) and range={yer} So basically the domain and range are both all real numbers.

Answer 3

how do u know this is a straight line

Answer 4

The function is in form of a linear equation...the graph represents a line. It's in the form y = mx + b
