If f(x) = 6x – 4, what is f(x) when x = 8?

Explanation: This question's it's about the function notation. Function notation is the equation can be written using function notation. Consider the function represented by the equation f(x)=6x-4 and f(x) when x=8.  

First rewrite the problem down.

Then you put by the value of x as the 8.

And then simplify and just gives us the final answer.

Don't forget to used f(x) gave us the final answer.

Hope this helps!

Thanks!

d. There is no slope.

Step-by-step explanation:

We know that slope =

For the given table, since there is no change in x coordinate .

Thus the change in x coordinate is 0.

Therefore, slope=

which means the slope does not exist.

Hence, (d) is the right option. There is no slope.
