Me find the domain to this expression

Hello from MrBillDoesMath!

Domain = {All real number except for x = 5}

Discussion:

The domain of a function is all points where the function is defined. In this case, as division by zero is not allowed . the domain is all real number except where x-5 = 0, i.e. x =5

Thank you,

MrB

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
