Hello!
The number 49 is similar to other numbers like 25, 81, 4, or 64. All these numbers are perfect squares. Perfect squares are numbers multiplied by itself. Here is a list of commonly used perfect squares.
- 1 × 1 = 1
- 2 × 2 = 4
- 3 × 3 = 9
- 4 × 4 = 16
- 5 × 5 = 25
- 6 × 6 = 36
- 7 × 7 = 49
- 8 × 8 = 64
- 9 × 9 = 81
- 10 × 10 = 100
- 11 × 11 = 121
- 12 × 12 = 144
From the list above, the square root of 49 is 7, but the question asks for the <u>negative</u><u> square root of 49</u>, which is written as: -√49.
To simplify this expression, first, simplify the radical, and then multiply the product by negative one.
7 × -1 = -7
Therefore, the negative square root of 49 is choice C, - 7.
Answer:
f(x) = -4
Step-by-step explanation:
Given function: f(x) = 4 + 4x - 4x²
Here, we are being asked to find the value of the function when x is equal to 2.
Substitute 2 as the value of x in the function and simplify:
⇒ f(x) = 4 + 4x - 4x²
⇒ f(2) = 4 + 4(2) - 4(2)²
⇒ f(2) = 4 + 8 - 4(4)
⇒ f(2) = 4 + 8 - 16
⇒ f(2) = 12 - 16
⇒ f(2) = -4
This means that when the value of x is 2, the value of the function is -4.
