A new parabola, g(x), is translated from f(x) using the translation T(-3, 7).
andriy [413]

Answer:

We can predict the vertex point of g(x) by vectorial sum, which is equal to V_{G}(x,y) = (h - 3, k + 7).

Step-by-step explanation:

The vertex of g(x) is equal to the vectorial sum of the vertex of f(x) and the translation vector:

V_{G}(x,y) = V_{F}(x,y) + T(x,y) (1)

Where T(x,y) is the translation vector.

If we know that V_{F} (x,y) = (h,k) and T(x,y) = (-3, 7), then the formula for the vertex of g(x) is:

V_{G}(x,y) = (h,k) +(-3, 7)

V_{G}(x,y) = (h - 3, k + 7)

ohaa [14]

Answer:

f(t) = 5t  

Step-by-step explanation:

distance = speed × time

          d = st     Insert value of speed

          d = 5t

In function notation,

Consider the function f(x)=−3x+3 on the interval [−8,4]. Find the absolute extrema for the function on the given interval. Expre
Nikitich [7]

By means of <em>functions</em> theory and the characteristics of <em>linear</em> equations, the <em>absolute</em> extrema of the <em>linear</em> equation f(x) = - 3 · x + 3 are 27 (<em>absolute</em> maximum) for x = - 8 and - 9 (<em>absolute</em> 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, <em>linear</em> equations have no absolute extrema for all <em>real</em> numbers, but things are different for any <em>closed</em> interval as <em>absolute</em> extrema are the ends of <em>linear</em> 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 <em>functions</em> theory and the characteristics of <em>linear</em> equations, the <em>absolute</em> extrema of the <em>linear</em> equation f(x) = - 3 · x + 3 are 27 (<em>absolute</em> maximum) for x = - 8 and - 9 (<em>absolute</em> minimum) for x = 4. (- 8, 27) and (4, - 9).
