As you can see in the picture below, it's not possible to create a triangle that has side lengths of 4, 8, and 3
triangle inequality theorem, impossible triangle
It turns out that there are some rules about the side lengths of triangles. You can't just make up 3 random numbers and have a triangle! You could end up with 3 lines like those pictured above that cannot be connected to form a triangle.
Answer:
f(3) = -4
Step-by-step explanation:
Draw a line parallel to the y-axis and cross point 3 on the x-axis. This line cuts the parabola at a point whose coordinates on the y-axis are f (3). This is -4.
Hope you understand.
