For each equation below find y if x = 2

Hey! Hope I can help!

a. y = 7 - ||, which if we fill in , then we get this equation: y = 7-2, and 7-2 = 5. y = 5.

b. y =  - 1, which if we fill in and multiply 2 to the power of 2, we get this equation: y = 4 - 1. 4 - 1 is 3. y = 3.

c. y = , which if we fill in and square root 2+14 (16), we get this equation: y = 4.
