Question

The graph of f(x) = x2 - 6x2 + 9x is shown.

Based on the graph, what are the solutions of the equation

a) x=4
b) x = -0,3
c) x = 0,3
d) x = -3, 0, 3

Answer 1

As it's a quadratic function the intercept on x axis are the solution.

The intercepts are

• (0,0)
• (3,0)

Hence solutions are

• 0 and 3

Answer 2

• C) x = {0, 3}

Explanation:

According to the diagram, the graph intersects or touches the x-axis at two points:

• (0, 0) and (3, 0)

The solutions are:

• x = [0, 3}

Correct choice is C
