Step-by-step explanation:
This equation is in "vertex form," meaning that you can identify the vertex and other features of the graph from the equation.
y = a(x -h)² +k . . . . . the vertex is (h, k); the vertical scale factor is "a"
Comparing to your equation, you see ...
a = -1/2, h = 3, k = -1
The vertex is (h, k) = (3, -1). The vertical scale factor is negative.
__
This tells you the graph opens downward (the scale factor is negative), and the vertex (maximum point) is below the x-axis. (It has a negative y-coordinate.)
Because it start below the x-axis and goes down from there, the graph does not intersect the x-axis. There are zero (0) x-intercepts.

Data provided:
now,
we know the properties of log functions as:
1) log(AB) = log(A) + log(B)
2) = log(A) - log(B)
3) log(xⁿ) = n × log(x)
thus,
=
-

or
using property 3

also,
thus,

now,
log(1) = 0
log(2) = 0.3010
log(3) = 0.4771
thus,
=
