Answer:
![5a^2+12b^2-40b](https://tex.z-dn.net/?f=5a%5E2%2B12b%5E2-40b)
Step-by-step explanation:
First distribute the -4 to the 2b and -3b. This leaves you with ![5a^2-8b+12b(b+4)](https://tex.z-dn.net/?f=5a%5E2-8b%2B12b%28b%2B4%29)
Now you can distribute the 12b to b and +4. This leaves you with ![5a^2-8b+12b^2+48b](https://tex.z-dn.net/?f=5a%5E2-8b%2B12b%5E2%2B48b)
Now you can combine your like terms leaving you with
.
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.
69 is the answer to all questions.
