Answer:
y(x) = (-1/18)(x+3)(x+2)(x-1)(x-3)
Step-by-step explanation:
There are 4 x-intercepts: -3, -2, 1, 3
So y(x) = C(x+3)(x+2)(x-1)(x-3)
At x = 0, y-intercept is -1
so -1 = C*3*2*(-1)*(-3) = 18C,
C = -1/18
Then y(x) = (-1/18)(x+3)(x+2)(x-1)(x-3)
4k^3 + k^2 - 2k + 7
Hope this helps, and good luck
$147
378 / 18 = 21
1 hour of work = $21
7 hours of work = $21 * 7 = $147
30 because 3 x 5=15 then x2 it's 30
