Question

The black graph is the graph of y=f(x). Choose the equation for the red graph.

Answer 1

y-1 = f(x)

Explanation:

Here, we want to choose the equation for the ref graph

The red graph as we can see is above the black

This means it is more positive

The difference between the two is just 1 unit

By the addition of 1 to the y-value of the black graph, we get the red

Thus, we have that;

y- 1 = f(x)
