Where would the following line cross the y-axis? f(x) = 2x - 4
O (0, 2)
O (2,0)
O (0, -4)
O (-4, 0)

Step-by-step explanation:

to find y-axis of the function we have to take 0 x and calculate it

according to the question:

another way to think about it

the function is a linear function i.e f(x)=mx+b where m is the slope (rate of change) and b is the y-intercept (where a line would cross y-axis)

our given function is f(x)=2x-4

using a little algebra we get

where -4 is y-intercept

hence,

the line of the function would cross y-axis at (0,-4) coordinate
