Find the zeros of the function f(x)=-x^2+49

x= -7, x=7

Explanation:

Set 49-

x

2

= 0 and factor

You'll get (x-7)(x+7)

You can check if you factored correctly by distributing or using F.O.I.L

Now you have to set (x-7)(x+7) equal to 0 and solve for x.

Treat them as two separate equations

So...

(x-7) = 0 (x+7) = 0

Once you solve for x you'll find that x is equal to 7 and -7 and these are your zeros.

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.
