3 seconds
solve for when y is zero
0 = -16t^2 + 32t + 48
0 = -16(x^2-2x-3)
0 = -16(x-3)(x+2)
x = 3 or -2
-2 is extraneous because time is not negative in this instance so 3 seconds.
Answer:
first one is d and the second is b

Answer:
Step-by-step explanation:
4x² + 76 = 32
4x² = -44
x² = -11
but x² must be non-negative, so there is no real solution.
Evaluate the given function in x=-4.
This is, replace the x in the function for -4 and find the value of g(-4).
The value of g(-4) is 32.
