Answer:
Step-by-step explanation:
1). x² - 10x + a²
By using the formula of (a - b)² = a² - 2ab + b²
x² - 2(5)x + a²
Therefore, for a perfect square of the expression a should be equal to 5.
Therefore, (x² - 10x + 25) will be the answer.
2). x² + 2ax + 36
= x² + 2(a)x + 6²
For a perfect square of the given expression value of a should be 6.
x² + 2(a)x + 6² = x² + 2(6)x + 6²
= (x + 6)²
Therefore, x² + 12x + 36 will be the answer.
3).
To make this expression a perfect square,
a² =
=
Therefore, the missing number will be .
<h2>Hello!</h2>
The answer is:
When the domain is -3, the range is -13.
<h2>Why?</h2>To solve the problem, we need to remember that the domain is also known as the input of the function, and the range of the function is also known as the output of the function.
We are given the inputs and we are asked to calculate the output of the function at -3, so, evaluating -3 into the function, we have:
Hence, we have that when the domain is -3, the range is -13.
Have a nice day!
