1. its -4 over x
Usually none. A function can be identified as f but it is more often denoted by f(x) to show that it is a function of x.
x/35 = 3/7 => x = 3/7 *35 = 3 * (35/7) = 3*5 = 15
No, y=x-2 is linear.
49 - x2 = -(x2 -49) = - (x-7)(x+7) divide by x -7 Answer: -(x+7) = -x-7
Y=8x-3
linear, if side is x then perimeter is 4x
Any function in which the dependent variable is not exactly proportional to the zeroth or first power of the independent variable. E.g.: y(x) = a*(x+x^3); y(x) = a*exp(x); y(x) = a*sin(x); etc. This may be extended to differential equations by stating a nonlinear differential equation is one in which some function depends on a derivative which is not to the zeroth or first power. An example is: dy/dx - (y(x))^2 = a. Note, all of the values for "a" in these examples are meant to be constants.
Yes, y=x^2 is a non-linear function. In fact it is a parabola. Graphing one is quite easy using a table of values or other methods.
In mathematics, when the dependent variable is not proportional to the independent variable. The function does not vary directly with the input. Example: y=sin (x).
A linear or non linear function is a function that either creates a straight line or a crooked line when graphed. These functions are usually represented on a table under the headings x and y.

Give us the whole equation, and we can help.
It is x - y + 2 = 0
An exponential function is a nonlinear function in the form y=ab^x, where a isn't equal to zero. In a table, consecutive output values have a common ratio. a is the y-intercept of the exponential function and b is the rate of growth/decay.
Y=x^2
No, it is not an example of a nonlinear relationship because there is a steady rate of change.
