which function has an inverse that is also a function? a. g(x) = 2x-3 b. k(x) = -9x2 c. f(x) |x+2| d. w(x) = -20
motikmotik

Answer:

A

Step-by-step explanation:

A function have the inverse only if it passes the horizontal line test ,

For the given options we need to look for the function which passes the horizontal line test

Option A is g(x)= 2x-3 which is a straight line with slope not equal to 0 so it passes the horizontal line test and hence it will have an inverse which is also a function.

Option B: we need to restrict the domain to get the inverse so the option B is not correct .

Option C : It also fails the horizontal line test .

Option D : Horizontal line so it also fails the horizontal line test .

Evaluate the expression: –(31 + 2) + 72 – (–5)2.
Rudiy27

Answer:

 14

Step-by-step explanation:

Order of operations rules require that we do any work inside parentheses first.  Thus,

–(31 + 2) + 72 – (–5)^2

becomes:

     -33    + 72 -  25, or

               14

Important:  Please use " ^ " to denote exponentiation; (-5)2 is incorrect, whereas (-5)^2 or (-5)² is correct.
