Answer:

ab = 21

Step-by-step explanation:

$(a - b)^2 = (a^2 + b^2 ) - 2ab\\\\4^2 = 58 - 2ab\\\\16 - 58 = - 2ab\\\\- 42 = - 2ab\\\\ab = \frac{-42}{-2} = 21$

For a given function ƒ(x) = x2 – x + 1, the operation –ƒ(x) = –(x2 – x + 1) will result in a

Mekhanik [1.2K]

Given:

The function is:

$f(x)=x^2-x+1$

To find:

The result of the operation $-f(x)=-(x^2-x+1)$ .

Solution:

If $g(x)=-f(x)$ , then the graph of f(x) is reflected across the x-axis to get the graph of g(x).

We have,

$f(x)=x^2-x+1$

The given operation is:

$-f(x)=-(x^2-x+1)$

So, it will result in a reflection across the x-axis.

Therefore, the correct option is A.
