Question

Find the zeros of the function.
f(x) = 9x2 - 27x + 20

Answer 1

Do you know what it means to find the zeros of a function?

Answer 2

no

Answer 3

It means that this is the place where the graph goes through the x axis. Something like theseI know those look crazy, but wherever the graph goes through the x axis is a zero of the function. You find the zeros of a function by factoring it, setting the factors equal to zero and solving for x. Like in this example\[x ^{2}+3x+2\]you can factor that to (x + 2)(x + 1), right?
