What is 1,258 rounded to the nearest thousand

By means of functions theory and the characteristics of linear equations, the absolute extrema of the linear equation f(x) = - 3 · x + 3 are 27 (absolute maximum) for x = - 8 and - 9 (absolute minimum) for x = 4. (- 8, 27) and (4, - 9).

<h3>What are the absolute extrema of a linear equation within a closed interval?</h3>

According to the functions theory, linear equations have no absolute extrema for all real numbers, but things are different for any closed interval as absolute extrema are the ends of linear function. Now we proceed to evaluate the function at each point:

Absolute maximum

f(- 8) = - 3 · (- 8) + 3

f(- 8) = 27

Absolute minimum

f(4) = - 3 · 4 + 3

f(4) = - 9

By means of functions theory and the characteristics of linear equations, the absolute extrema of the linear equation f(x) = - 3 · x + 3 are 27 (absolute maximum) for x = - 8 and - 9 (absolute minimum) for x = 4. (- 8, 27) and (4, - 9).

Find f(–2) for the function f(x) = 3x2 – 2x + 7. −13 −1 1 23

Elan Coil [88]

Answer:

Step-by-step explanation:

$f(x)=3x^2-2x+7\\\\f(-2)\to\text{put x = -2 to the equation of a function:}\\\\f(-2)=3(-2)^2-2(-2)+7=3(4)+4+7=12+4+7=23$
