HELP Please!!!

Mathematics
2 answers:

Answer:

1. false

2. false

3. true

Step-by-step explanation:

1. If the value of a was negative, then the graph of the quadratic would open downwards because the negative sign would induce a reflection of the graph over the x-axis.

However, we can see from the graph that the quadratic opens up, so a is not negative and this statement is false.

2. The vertex of a quadratic equation is the minimum or maximum point. Here, since the graph points up, the vertex will be the minimum point. That point is actually (3, -1). Clearly, this is not (-1, 3), so the statement is false.

3. The axis of symmetry is essentially the line with the x-value of the vertex. Since the x-coordinate of the vertex is 3, that means the axis of symmetry is the line x = 3. Thus, the statement is true.

What is 3log2 x-(log2 3-log2(x+4)) written as a single logarithm?
zloy xaker [14]
Answer:
log₂(\frac{x^2(x+4)}{3})

Explanation:
Before we begin, remember the following:
logₐ(x) - logₐ(y) = logₐ(\frac{x}{y})
alog(x) = log(xᵃ)

Now, for the given we have:
3 log₂(x) - (log₂3 - log₂(x+4))
log₂(x²) - log₂(\frac{3}{x+4})

log₂(\frac{x^2}{ \frac{3}{x+4} }) = log₂(\frac{x^2(x+4)}{3})

Hope this helps :)
