Question

The graphs of linear functions fand g are shown on the grid.

which function best represented by the graph of g

Answer 1

g(x) = 3f(x)

Explanation:

We can see that for function g;

When x = 1, y = 3

When x = 2, y = 6

When x = -1, y = -3

When x = -2, y = -6

For function f;

When x = 1, y = 1

When x = 2, y = 2

When x = -1, y = -1

When x = -, y = -2

We can see that the output of g(x) is always 3 times that of f(x) for same values of x.

Thus;

g(x) = 3f(x)
