It should be 5/13 because the opposite angle from D is 12, which you would use if you are looking for sine. But, since you are looking for cosine, it is adjacent over hypotenuse. Therefore leaving you with 5/13, since your hypotenuse is always your longest side and the adjacent is the other side from the one opposite of the angle.
The equivalent value of the function f(x) = –2x^2 – 3x + 5 if x = -3 is -4
We are to evaluate the function f(x) = –2x2 – 3x + 5 for the input value –3.
Given the function:
For x = -3, we will have to substitute x = -3 into the expression to have:
f(-3) = –2(-3)^2 – 3(-3) + 5
f(-3) = -2(9) + 9 + 5
f(-3) = -18 + 14
f(-3) = -4
Hence the equivalent value of the function f(x) = –2x^2 – 3x + 5 if x = -3 is -4
