What is "if c(x) = 4x – 2 and d(x) = x2 + 5x?

The functions given are c(x) = 4x - 2 and d(x) = x^2 + 5x.

1. c(x) = 4x - 2: This function is a linear function, where the coefficient of x is 4 and the constant term is -2. It represents a straight line with a slope of 4 and y-intercept of -2.

2. d(x) = x^2 + 5x: This function is a quadratic function, where the highest degree term is x^2. The coefficient of x^2 is 1, and the coefficient of x is 5. The function represents a parabolic curve that opens upwards.

These two functions can be used to perform various mathematical operations such as addition, subtraction, multiplication, and division, and can also be plotted on a graph to visualize their behavior and relationship.
