please help me with this, I don't need the work just which one it is... please and thank you!!

Ar A differentiable function has the value y(3) = -1 and the derivative value y'(3) = 2. Approximate the value of y(2.9). If f (x) = sin x cos x, what is f' (x)? o y(2.9) ~ 1.2 of'(x) = -sin x - cos2x o y(2.9) ~ 1.7 of' (x) = sinx - cos2x o y(2.9) ~ -1.2 of' (x) = sin x + cos2x 50 o y(2.9) ~ -1.5 39 of' ( x ) = -sin x + cos2x Which of the following is true? A differentiable function has the value y(-1) = 1 and the derivative value y:(-1) = 2. Approximate the value of y(-1.1). O If f '(x) is positive, and f "(x) is 0, then f (x) is flat and f is concave up. o y(-1.1) ~ 0.8 If f '(x) is positive, and f "(x) is 0, then f (x) is decreasing and f is concave up. o y(-1.1) ~ -0.8 o y(-1.1) ~ -1.0 If f '(x) is positive, and f "(x) is 0, then f (x) is flat and f is concave down. o y(-1.1) ~ 1.2 40 If f '(x) is positive, and f "(x) is 0, then f (x) is increasing and f has no concavity. If f(x) = sin x, which of the following is true? of'(x) = () Which of the following is true? 4.7 di of' ( x ) = df (x) O If f(x) is decreasing and f "(x) is positive, then f '(x) is positive and f is concave up. dx of' ( x ) = dy O If f(x) is decreasing and f "(x) is positive, then f '(x) is negative and f is concave down.
