Answer:
first 2 options and 5th option are true
Step-by-step explanation:
locate y = - 4 on the y- axis. then a horizontal line through y = - 4 intersects the curve at x = - 2 and x = 1
----------------------------------------------------------
the axis of symmetry is a vertical line through the vertex with equation
x = c ( c is the value of the x- coordinate of the vertex )
vertex = ( - [tex]\frac{1}{2}[/tex], - 6 )
equation of axis of symmetry is x = - [tex]\frac{1}{2}[/tex]
------------------------------------------------------------
the minimum value is the y- coordinate of the vertex
that is the minimum value of f(x) is - 6
------------------------------------------------------------
given a parabola in standard form
ax² + bx + c ( a ≠ 0 )
• if a > 0 then graph opens up
• if a < 0 then graph opens down
Here the graph opens up , then coefficient of f(x) is positive
-------------------------------------------------------------
the solutions to f(x) = 0 are the values of x on the x- axis where the graph crosses.
the solutions are x = 2 and x = - 3
