F (x) =2x -4; find f (-4)

NemiM [27]

Answer:

f(-4) = -12

Step-by-step explanation:

$f(x)=2x-4$

To calculate f(-4), we need to substitute x in our equation above with -4:

$f(x)=2x-4\\f(-4) = 2*(-4) - 4\\f(-4) = -8-4 = -12$

Note that 2*(-4) = -8

Answer: f(-4) = -12

What is the slope of these two equations?

Juli2301 [7.4K]

Answer:

8. 0

9. undefined

Step-by-step explanation:

8. 0

> because the y variable is the same for all x-values, this is a horizontal line. Horizontal lines have a slope of 0.

> Thinking of slope as rise over run: we will always rise 0, and run __ from any two points--0 divided by any number is always 0

9. undefined

> because the x variable is always the same, no matter what y variable we graph, we will have the same outcome. So, this would look like a straight line, which have an undefined slope.

> If you think of a slope as rise / run; if you go from any two points, there will be a 0 in the denominator--which is undefined

hope this helps!! have a lovely day :)
