Graphs of functions on the interval [−4, 4] are depicted below. For each function, find: 1) The domain 2) Zeros of a function (the values of x where the function is zero) 3) Intervals where the function is positive and intervals where it is negative

1/4 because there is 4 grades.

40 minutes

step-by-step explanation:

add the time and multiply by 2

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
