Answer:
Option D
Step-by-step explanation:
Given is a table which gives the order pair of x and y for a function f(x)
We have to find the local minimum of the function f(x)
We have from the table the values of different f(x)
Of all we find the least value is -15 and for this x value is -2 or +2
Hence f(x) has minimum at two points
(-2,-15) and (2,-15)
Out of 4 options given we find that (2,-15) appears in IV option
Hence option D is right answer
Use<span> your calculator to </span>find the value<span> of and the triangle to set up the ratio on the right. Solving the equation and rounding to the nearest tenth gives you . To </span>find<span> y, you can either </span>use<span> another </span>trigonometric function<span> (such as </span>cosine<span>) or you can </span>use <span>the Pythagorean Theorem.</span>
