• 2, 5
• 0, 7
• no real solution

Use the graph of f(x) to find the real solutions of f(x)=0.

• 0, 5
• -2
• 0, -4
• no real solution

What is another way to say "where a function crosses the x-axis"?

• x-intercept
• zero
• root
• all of these.

What are the zeros (x-intercepts)?

• x = 4, 7
• x = -1, 4/7
• x = -4/7, 1
• x = 7, -4

True or false:
The solution, root, x-intercept, and zero of a problem are all the same thing.

• True
• False, because the solution and root are the same but the x-intercept and zero are different
• False, because the x-intercept and root are the same but the zero and solution are different
• False, they are all different
