Find the zeros of the function. f(x) = 9x2 + 6x - 8

1 answer:

8 0

To find the zeros of a function, you can use a graph and find where the function goes through the x-axis. If you cannot use a graph you can factor the function and solve for x like this:

9x^2 + 6x - 8 = (3x - 2)(3x + 4)

Now solve for x:

3x - 2 = 0
3x = 2

x = 2/3

3x + 4 = 0
3x = -4
x = -4/3

So the zeros are x = 2/3 ; -4/3

Roam can build 18 tables 300 plus the 60 he already had and then you divide it by 20 since that’s how much he needs for 1 table which means he can make 18 after dividing

Just isolate the y in both cases:
4y=-3+2x, y=-3/4+1/2x
-2y=-3x+4, y=3/2x-2
