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.

A triangle has two 52° angles and one 76° angle. What kind of triangle is it?
r-ruslan [8.4K]

Answer:

Isosceles triangle

Step-by-step explanation:

There are three different kinds of triangle: equilateral, isosceles, and scalene.

-Equilateral triangles are triangles where all 3 sides and angles are the same. (First image)

-Isosceles triangles are triangles where 2 of the sides and angles are the same, while the third side and angle is different. (Second image)

-Scalene triangles are triangles where all 3 sides and angles are different. (Third image)

In the case of this triangle, two of the sides have the same 52 degree angle. They would also have the same side lengths, and <u>thus be a isosceles triangle. </u>

Hope this helps! :3
