Find the greatest maximum y-value of the following equation:

1 answer:

5 0

A quick way to do this is by recalling the fact that $-1\le\cos x\le1$ , so the largest value that $\cos ax$ alone (for any real value of $a$ ) can take on is 1.

This means $-3\le3\cos2x\le3$ , and so $1\le3\cos2x+4\le7$ .

So the maximum value of this function is 7.

Answer:

Step-by-step explanation:

y = (-2/5)x + 1

By inspection of the equation, the slope of the line is -2/5 and the y-intercept is 1.

Therefore, we can immediately discount option B and D, as their y-intercepts are NOT 1.

Find the point where the line crosses the x-axis by setting the equation to 0 and solving for x:

0 = (-2/5)x + 1

⇒ -1 = (-2/5)x

⇒ -5 = -2x

⇒ x = 5/2

Therefore, the line of the function intersects the x-axis at x = 5/2 = 2.5

From inspection of the graphs, the line in option A intersects the x-axis at 2.5. Therefore, this is the correct graph.
