Question

What are the zeros of the graphed function y =
{(x +
3)(x + 5)?
6
O-5 and -3
5
O 5 and 3
O-8 and 5
O 0 and 5

Answer 1

Answer:

-3 and -5

Step-by-step explanation:

The zeros are where the line touches the x-axis

From the graph we can see that the line touches those points.

You can also determine it from the equation because the equation is in factored form, which is (x-r1)(x-r2)

Remember that it is minus so although it is +3 and +5 the actual zero is negative!!

Answer 2

-5 and -3 because it’s a parabola so whichever two or more is on the x-axis will be your zeros
