Use the graph that shows the solution to f(x) = g(x).
f(x) = - *x² + 3x + 1
g(x) = x - 1
f(x)
ox)
What is the solution to f (x) = g(x)?

-3-2
x = 0
x = 2
f(x)

g(x)

Answer 1

x = 4

Explanation:

Both A and B are similar

We have no problems with f(x) as it is similar on both plots

A graph of g(x) however shows that it is the second plot that is correct

Thus,

To get the solution , we need the point at which both graphs crosses each other

we can see this at the point x = 4 and thus that is our solution
