Answer:
Step-by-step explanation:
(-5,-3) is a point on the graph.
f⁻¹(-3) = -5
That is negative since the elevator is decreasing. If the elevator was going up, it would be positive.
<span>Given the quadratic equation: f(x) = -2x^2 - 2x - 1, the axis of symmetry can be obtained by finding the line that divides the function into two congruent or identical halves. Thus, it should pass through the vertex and is equal
to the x-coordinate of the vertex. </span>
<span>Note that a quadratic
equation in standard form: y = ax^2 + bx + c, has the vertex located at (h,k) where, h = -b/2a and k is determined by evaluating y at
h. In this case, a = -2, b = -2, thus, h = -0.5, k = 0.5. Thus, the vertex is located at (-0.5, 0.5) and the axis of symmetry is at x = -0.5. </span>
Answer:
Your answer would be c 18=2x
Step-by-step explanation:
Because you done did 3x=9 which you now have to do the other end of the problem.
