Answer:

C

Step-by-step explanation:

functions can only have domains that are different numbers, (first number) the rest repeat the domain and that makes it not a function

Answer:

C

Step-by-step explanation:

A set of pairs is a function if and only if there is only <em>one</em> y-value for each x-coordinate. In other words, the x-coordinate <em>cannot </em>repeat. If it does, then it must equal the same thing.

Let's go through each of the choices.

For A, -5 repeats twice. It simultaneously equals both 4 and -2. This cannot be true if this is a function, so A is not correct.

For B, 2 repeats twice. It equals both 6 and -6. So, this is also not a function.

For C, no digits are repeating. Thus, this is a function.

To make sure, in D ,-3 is repeating. It is both -4 and 8, so this is not a function.

So, our answer is C.

And we're done!

Work out m and c for the line:2y+3x=5
Gekata [30.6K]

Step-by-step explanation:

General line equation: y = mx + c.

2y + 3x = 5

2y = -3x + 5

y = -1.5x + 2.5

Hence m = -1.5 and c = 2.5.

#6: Tell whether the function below is 1 point<br> linear or exponential.<br> *<br> f(x) = -1/4x + 5
Pachacha [2.7K]

Answer:

Linear function

Step-by-step explanation:

Given

f(x) = -\frac{1}{4}x + 5

Required

Linear or Exponential

A linear equation has the form: f(x) = mx + c;

An exponential has the form: f(x) = ab^x

By comparing both functions to: f(x) = -\frac{1}{4}x + 5

The linear function is similar to f(x) = -\frac{1}{4}x + 5

<em>Hence, the given function is a linear function.</em>
