The parabola opens upward with the y- intercept being at y=7 (0,7) and the x- intercepts on x= -2,-4 / (-2,0), (-4,0). The axis of symmetry is on x=-3, and the vertex is on (-3,-1).
The correct answer is C. scale
Scale is an item for measuring weight, while the other ones are all units of measurement.
Answer: 125x125
Step-by-step explanation:
Answer:
x = 1 , 2.
Step-by-step explanation:
I am assuming these are logs to the base 3.
log3 x + log3 (x^2 + 2) = 1 + 2log3x
-log3 x + log3 (x^2 + 2) = 1
log3 [ (x^2 + 2) / x] = 1 NOTE: 1 = log3 3, so:
log3 [(x^2 + 2) / x] = log3 3
(x^2 + 2) / x = 3
x^2 - 3x + 2 = 0
(x - 1)(x - 2) = 0
x = 1 , 2.
To find the inverse, interchange the variables and solve for y.
