Answer: B: (1-5x²)³, all real numbers
Step-by-step explanation:
The notation is called function composition, which is where you pass one function in as the value of another function. In other words,
.
Since we have the values for f(x) and g(x), let's plug them in.
Hence, the best answer choice is B, as all real numbers would work and it is the cube of 1 - 5x².
Answer:
, n < -16
Step-by-step explanation:
To write this into an inequality you need to recognize keywords. The first keyword is "sum" this means the two numbers must be added; so the first part of the inequality is 4+n. Then, it says the sum is "divided by" 2; this means both numbers must be put over two like . Finally, this is "less than" negative. Therefore, this must be an inequality with a sign opening towards -6. So the final answer is
.
To solve the inequality isolate the variable. Multiply both sides by 2, so the new inequality is . Next, subtract 4 from both sides. The answer is n < -16.
