These equations represent two different functions. The correct answer is f( x) = 3 x 2 + 5 and y = 3 x 2 + 5. They do not produce the same graph, so they are not the same function. The second function has a slope of −2 and a y-intercept of 7. The first has a slope of 2 and a y-intercept of −7. These equations look similar but are not the same. Which two equations represent the same function? This would make it easy to graph both functions on the same graph without confusion about the variables. You could write the formula for perimeter, P = 4 s, as the function p( x) = 4 x, and the formula for area, A = x 2, as a( x) = x 2.

This can be a helpful way to distinguish equations of functions when you are dealing with more than one at a time. Instead, you could use f( x) or g( x) or c( x). This is the same as the equation as y = 4 x + 1.įunction notation gives you more flexibility because you don’t have to use y for every equation.

Mathematically speaking, x is the input, or the “independent variable,” and f( x) is the output, or the “dependent variable,” since it depends on the value of x.į ( x) = 4 x + 1 is written in function notation and is read “ f of x equals 4 x plus 1.” It represents the following situation: A function named f acts upon an input, x, and produces f( x) which is equal to 4 x + 1. If you put x into the box, f( x) ,comes out. You can also call the machine “ f” for function. The number that goes in is called the input, and the number that is produced is called the output.

Again, we can substitute the value of y from the second equation into the third.

Now we can find the point of intersection of the second and third lines. The point of intersection of the first two lines is (-1,1). We can solve the system of equations by substituting the value of y from the second equation into the first. Let's consider the first and second lines. In other words, the point of intersection of the first two lines must be the point of intersection of the second and third lines. If the point of intersection lies on all three lines, then we should be able to select any two lines, find their point of intersection, and come up with the same point of intersection each time.
