1 answer:
Nikitich [7]3 years ago
6 0

Answer:

(1,-8), (-6,-4), (3,7), (-6,1)

Step-by-step explanation:

In a function the x values cannot repeat. Look at each answer choice and see if an x repeats:

The first choice (top left) has the x value, -6, repeating. It cannot be a function.

The second choice (top right) does not have an x value repeat. This makes it a function!

The third choice, (bottom left) does not have an x value repeat. This makes it a function!

The fourth choice, (bottom right) does not have an x value repeat. This makes it a function!

2. Determine if either of the following equations are functions? Draw the graphs and explain how
nekit [7.7K]

Answer:

Both equation represent functions

Step-by-step explanation:

The function is the relation that for each input, there is only one output.

A. Consider the equation

y=-\dfrac{3}{5}x+2

This equation represents the function, because for each input value x, there is exactly one output value y.

To check whether the equation represents a function, you can use vertical line test. If all vertical lines intersect the graph of the function in one point, then the equation represents the function.

When you intersect the graph of the function y=-\dfrac{3}{5}x+2 with vertical lines, there will be only one point of intersection (see blue graph in attached diagram). So this equation represents the function.

B. Consider the equation

y=x-x^2

This equation represents the function, because for each input value x, there is exactly one output value y.

When you intersect the graph of the function y=x-x^2 with vertical lines, there will be only one point of intersection (see green graph in attached diagram). So this equation represents the function.
