For the graph of the function, identify the axis of symmetry, vertex and the formula for the function.
Axis of symmetry: x=-0.5; Vertex: (-0.5, 0.75): f()=x2 + x
O Axis of symmetry: x=-0.5: Vertex: (-0.5, 0.75): f(x) = x2 +x+1
O Axis of symmetry: x=-0.5; Vertex: (-0.5, -0.75): f(x) = x²-x+1
O Axis of symmetry: x=-0.5: Vertex: (-0.5.0.75): f(x) = x2 + 2x + 1

step-by-step explanation:

ever thing time 1 is a multiply by 1 it get  

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
