Multiply the -2 with whats inside the brackets first, then simplify the equation.
-8x + 8 + x
-7x + 8
Notice the picture below
keep in mind, a regular hexagon, splits a circle in 6 equal angles
Answer:
110°
Step-by-step explanation:
Zeros: x = 2, x = 4
Turning point: (halfway between the zeros) x = 3, y = -1
y-intercept: where x=0, at f(0) = 8.
Axis of symmetry: the vertical line through the turning point: x = 3.
