The equation that describes the graph is the one in option a:
f(x) = 2*|x - 3| + 1
Which equation represents the graph?
We can see that the graph is an absolute value equation with a vertex in the point (3, 1), so the absolute value function must be of the form:
f(x) = a*|x - 3| + 1
Now, we also can see that the arms open upwards, so the slope must be positive, and we can see that for each increment in x, we have an increment of 2 units in y, so the slope is a = 2.
This means that the function is:
f(x) = 2*|x - 3| + 1
So the correct option is a.
