The graph of f(x) = -x2 - 2x + 8 is shown. Which of the following describes all solutions for f(x)?
morpeh [17]

Answer:

(x, x2 -2x+8) where −5 ≤ x ≤ 3

Step-by-step explanation:

The given function is  f(x)=x2- 2x+ 8

We want to select the option that describes all the solutions to the parabola.

The domain of the parabola is −5 ≤ x ≤ 3.

This means that  any x=a on −5 ≤ x ≤ 3 that satisfies (a,f(a)), is a solution.

This can be rewritten as (a,-a2- 2a+ 8)

Therefore for x belonging to −5 ≤ x ≤ 3, all solutions are given by:

(x, x2 -2x+8) where −5 ≤ x ≤ 3.

CAN YALL PLEASE WORK IT OUTTT <br><br> $18.79 + $2.11 + ‐$1.92 + $17.28
Dmitry [639]

Answer:

40.1

Step-by-step explanation:

Because the order of operations (Bodmas or Pedmas) tells you to add from left to right. So you would do 18.79 + 2.11 = 20.9, then you would do 20.90 + 1.92 (Add 0 at the end of 20.9) = 22.81. Then you will add 22.81 + 17.28 = 40.1. So your answer is 40.1. Hope this helps!
