Substitute in 2 for x in the equation:

f(2) = 2^2 + 5(2) - 8

= 4 + 10 - 8

= 6

Then, substitute in 6 for x in the equation:

f(6) = 6^2 + 5(6) - 8

f(6) = 36 + 30 - 8

= 58

To find the average rate of change, take the values you got from substituting the x-values in from above, then divide by the difference of the x-values:

(f(6) - f(2)) / (6-2)

= (58-6) / (6-2)

= 52/4

= 13

The function f(t)=t^2+12t-18 represents a parabola.

Lyrx [107]

$y= t^{2} +12t -18 \\ y+18=t^{2} +12t \\ y+18+36=t^{2} +12t+36 \\ y+54=(t+6)^{2} \\ y=(t+6)^{2} -54$
$f(t) = (t+6)^{2} -54$
