Answer:
a) (-2,-1) b) (-3,0) & (-1,0)
Step-by-step explanation:
For the first part, the turning point is simply where the graph curves. We can see that that happens on (-2, -1).
For the second part, the roots of the equation are simply when the graph crosses the x-axis. This happens twice, at (-3,0) and (-1,0)

Answer:
3(m+8)
Step-by-step explanation:
first you add m to 8, so you would do m+8. then you triple that, means multiply it by 3. so 3(m+8)
Answer:
Step-by-step explanation:
Using log(x) - log(y) = log (x/y)
logx^2 - log(x+6) = 1 is equal to:
log (x^2/(x+6)) = 1
Taking inverse base 3 log on both side:
x^2/(x+6) = 3
x^2 = 3x + 18
x^2 - 3x - 18 = 0
(x-6)(x+3) = 0
x = 6 or -3
