A linear function is increasing if it has a positive slope.
To find this easily, put the function into the form y=mx+b. If m is positive, the function is increasing. If m is negative, it is decreasing.
No. An exponential function is not linear. A very easy way to understand what is and what is not a linear function is in the word, "linear function." A linear function, when graphed, must form a straight line.P.S. The basic formula for any linear function is y=mx+b. No matter what number you put in for the m and b variables, you will always make a linear function.
It will just be the gradient of the function, which should be constant in a linear function.
It is a continuous function. If the line is a straight line, it is a linear function.
The inverse of a linear function is always a linear function. There are a few ways to approach this.To think about it, you can imagine flipping the x and y axes. Essentially this equates to turning the graph of the linear function on its side to reveal the new inverse function which is still a straight line.More rigorously, the linear function y = ax + b has the inverse equation x = (1/a)y - (b/a). This is a linear function in y.

No, not all linear functions are increasing. A linear function can have a positive slope, in which case it is increasing; a negative slope, making it decreasing; or a zero slope, which means it is constant. The slope of the function determines its behavior—specifically, whether it rises, falls, or remains flat as the input increases.
No, a linear function does not increase faster than an exponential function. While linear functions grow at a constant rate, exponential functions grow at an increasing rate, meaning that as the input value increases, the output of the exponential function will eventually surpass that of the linear function. For sufficiently large values of the input, the exponential function will outpace the linear function significantly.
The slope of a linear function is also a measure of how fast the function is increasing or decreasing. The only difference is that the slope of a straight line remains the same throughout the domain of the line.
A function that is linear, discrete, and increasing can be represented by the equation ( f(x) = mx + b ), where ( m > 0 ) (ensuring it is increasing) and ( x ) takes on discrete values, typically integers. In this case, the function will produce a series of points that form a straight line with positive slope when plotted. The discrete nature means that the function is only defined for specific values of ( x ), such as ( x = 0, 1, 2, \ldots ).
Assuming the function is linear, the direction of the function can be determined by the coefficient's sign:[y = mx + b]Where m is the coefficient of x, if m is negative, then the function is increasing. If m is positive, the function is decreasing (this relationship is rather complicated and requires advanced calculus to prove).
No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.
Assuming the domain is unbounded, the linear function continues to be a linear function to its end.

No. A function need not be linear. For example, y = sin(x) is a function of x but it is not a linear equation.
