Determine the points in the interval (0, 2) at which the graph of the function below has a horizontal tangent line. f(x) = 6 cos x + 3 sin 2x

There are 3 points

f(x) = 6 cos x + 3 sin 2x

There are 3 points

Step-by-step explanation:

Determine the points in the interval (0, 2) at which the graph of the function below has a horizontal tangent line.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
