Question

2. f(x) = 3ǀ2x - 1ǀ + x, what is the output for the input -4?
im stumped pls help

Answer 1

output = 23

Explanation:

x = -4

f(x) = 3ǀ2x - 1ǀ + x

f(x) = 3ǀ2(-4) - 1ǀ + (-4)

f(x) = 3ǀ2(-4) - 1ǀ - 4

f(x) = 3ǀ-8 - 1ǀ - 4

f(x) = 3ǀ-9ǀ - 4

f(x) = 3(9) - 4

f(x) = 3(9) - 4

f(x) = 27 - 4

f(x) = 23
