Option A). 7, -4 and 1/3
To find the zeros you can factor the polynolial into (3x-1)((x+4)(x-7)
Then:
3x -1 =0 => x = 1/3
x+4=0 => x = -4
x-7 =0 => x =7
Those are the three zeros.
To find an inverse function first replace f(x) with y
f(x) = 8*sqrt(x)
y = 8*sqrt(x)
Then, simply switch the places of the x and y.
x = 8sqrt(y)
Now solve for the new y by squaring both sides (to get rid of the root)
x^2 = 64y
divide to get
y = x^2/64. This is the inverse function or option C.
X= -28
-2.5(-28) = 70

Answer:
x = -12
Step-by-step explanation:
-1/4x - 12 = x + 3
-x - 48 = 4x + 12
-x -4x = 12 + 48
-5x = 60
x = -12
