Evaluate the expression for x=1,y=4 and z =-2. Write your answer as an integer or round to the nearest hundredth , if needed.

Step-by-step explanation:

Putting values of x y and z in the expression

2(1) - [(1)(4) + 1]2 - (-2)

2 - (4+1)2 + 2

2 - (5)2 + 2

2 - 25 + 2

-23 + 2

-21

The function 2^x is exponential.

It keeps growing as x goes to + infinity so it does not have horizontal asymptote to the right.

The limit of 2^x when x goes to - inifinity is 0,so y = 0 is a horizontal asymptote.

It does not have vertical asymptotes because the function is defined for all the real x values.

y = 0
