If f(x)=2x-4 and x=4

Solve for f(x):

4

Step-by-step explanation:

f(x)=2x-4

Just plug in 4 into x. If you get confused on what f(x) means, it basically is the output value or the y value. So when plugging in the number for f(x), I recommend not worrying about the symbol f(x) too much.

a) 0

step-by-step explanation:

i^413 x i^0 = 0 as any number multiplied by a zero is

pls mark as brainliest.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
