Answer:
B) The base graph has been reflected about the y-axis
Step-by-step explanation:
We are given the function,
.
Now, as we know,
The new function after transformation is
.
<em>As, the function f(x) is changing to g(x) = f(-x)</em> and from the graph below, we see that,
The base function is reflected across y-axis.
Hence, option B is correct.
Answer:

Step-by-step explanation:
1. Expand by distributing sum groups.
2. Expand by distributing terms.

3.Expand by distributing terms.

4. Remove parentheses.

5. Collect like terms.

6. Simplify.

Thus. the answer is,

It has to have x decreasing and y decreasing, along with x getting bigger while y gets smaller, and it has to cross x at -5, 0, and 4 so this is your graph
Answer:
tan2θ = 4√2/7
Step-by-step explanation:
Given sin theta=1/3 and 0 < theta< π/+
Required
tan 2 theta
tan2 theta = 2tanθ/1-tan²θ
Get tan θ
sinθ = opp/hyp
adj = √3²-1²²
adj = √9-1
adj = √8
tanθ = opp/adj = 1/2√2
tan2 theta = 2(1/2√2/1-(1/2√2)²
tan2θ = 1/√2/1-1/8
tan2θ = 1/√2/7/8
tan2θ = 8/7√2
Rationalize
tan2θ = 8√2/14
tan2θ = 4√2/7
I would go with A. An estimate.
This may not be the right answer but Good Luck!
