Graph h (x) = 3 cos (2x) - 1 Use 3.14 for T. Use the sine tool to graph the function. The first point must be on the midline and
the second point must be a maximum or minimum value on the graph closest to the first point.
1 answer:
Answer:
See attachment
Step-by-step explanation:
We want to graph .
We can graph this function easily by applying transformations to the parent function.
The base function is
The transformed function has an amplitude of 3 but is shifted 1 unit down, so the minimum value is -4 and the maximum is 2.
The function is shrunk horizontally by a factor of 1/2.
The graph of the transformed function is shown in the attachment

Answer:
(x + 6, y + 0), 180° rotation, reflection over the x‐axis
Step-by-step explanation:
The answer can be found out simply , a trapezoid has its horizontal sides usually parallel meanwhile the vertical sides are not parallel.
The horizontal parallel sides are on the x-axis.
Reflection over y- axis would leave the trapezoid in a vertical position such that the trapezoid ABCD won't be carried on the transformed trapezoid as shown in figure.
So option 1 and 2 are removed.
Now, a 90 degree rotation would leave the trapezoid in a vertical position again so its not suitable again.
In,The final option (x + 6, y + 0), 180° rotation, reflection over the x‐axis, x+6 would allow the parallel sides to increase in value hence the trapezoid would increase in size,
180 degree rotation would leave the trapezoid in an opposite position and reflection over x-axis would bring it below the Original trapezoid. Hence, transformed trapezoid A`B`C`D` would carry original trapezoid ABCD onto itself
