Answer:

Step-by-step explanation:
Because of the power of a power property, which states that
, where m and n are real numbers, the expression you mentioned can be simplified by applying this property like this: 
answer

explanation
since there are 2 x-intercepts, the lowest degree the function could possibly have is 2, so this could be the graph of a parabola
since our zeros are at x = 4 and x = -2, our factors are (x - 4) and (x + 2)
our equation so far is
(x - 4)(x + 2)
= 
= 
since the function is reflected across the x-axis, multiply the equation by -1

= 
since the function has a vertical stretch of 3, multiply the equation by 3

=
