What is "if a(x) = 3x + 1 and b (x) = startroot x minus 4 endroot?

The functions given are:

a(x) = 3x + 1 b(x) = √(x - 4)

Function a(x) is a linear function with a slope of 3 and a y-intercept of 1. It represents a straight line where the output (y) increases by 3 units for every 1 unit increase in the input (x).

Function b(x) is a square root function where the input is restricted to x ≥ 4 to ensure that the square root is non-negative. This function represents a curve that starts at the point (4, 0) and moves upwards as x increases.

Both functions have different characteristics and behaviors, but can be used in mathematical operations such as addition, subtraction, multiplication, and division to create more complex functions.
