Function h(x) = f(x) – g(x) = -x - 4
What is a function?
Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given functions
f(x) = 8x – 2
g(x) = 9x + 2
h(x) = f(x) – g(x)
h(x) = (8x – 2) - (9x + 2)
h(x) = 8x - 2 -9x - 2
h(x) = (8x - 9x) + (-2 - 2)
h(x) = -x - 4
Hence, h(x) = -x - 4
