Answer: top right

Explanation:

if you do the vertical line test you can see that it’s the only graph where each x value has one y value, indicating that it’s a function

Answer:

The second graph

Explanation:

The general function is f(x) = mx + c

${ \tt{m = (8 - 4)/(4 - 2) = (4)/(2) }} \\ \\ { \underline{ \tt{ \: m = 2 \: }}}$

For y-intercept:

${ \tt{f(x) = mx + c}}$

consider point (2, 4)

${ \tt{4 = (2 * 2) + c }} \\ { \tt{c = 0}}$

Function:

${ \boxed{ \tt{f(x) = 2x}}}$
