Answer:
tasha got 1/2 of it
one friend got 1/4 of it
the other friend got 1/4 of it
Step-by-step explanation:
y = x³ + 3x² - x - 3
0 = x³ + 3x² - x - 3
0 = x²(x) + x²(3) - 1(x) - 1(3)
0 = x²(x + 3) - 1(x + 3)
0 = (x² - 1)(x + 3)
0 = (x² + x - x - 1)(x + 3)
0 = (x(x) + x(1) - 1(x) - 1(1))(x + 3)
0 = (x(x + 1) - 1(x + 1))(x + 3)
0 = (x - 1)(x + 1)(x + 3)
0 = x - 1 or 0 = x + 1 or 0 = x + 3
+ 1 + 1 - 1 - 1 - 3 - 3
1 = x or -1 = x or -3 = x
Solution Set: {-3, -1, 1}
So, y-intercept is (0,3) and x-intercept is (3/7,0)
Step-by-step explanation:
We are given:

We need to find y-intercept and x-intercept
Finding y-intercept
To find y-intercept we put x =0
Solving:

So, y-intercept is (0,3)
Finding x-intercept
To find x-intercept we put y =0
Solving:

So, x-intercept is (3/7,0)
So, y-intercept is (0,3) and x-intercept is (3/7,0)
