1969 AB 1 Consider the next functions described for all by:

f1 ( x) = x farreneheit 2 ( x) = x cos x f3 ( x) = 3e2 x f 4 ( x) = x в€’ x

Answer the following inquiries (a, b, c, and d) regarding each of these functions. Indicate your answer by writing possibly yes or no in the suitable space in the given rectangular grid. Zero justification is necessary but every single blank space will be scored as the wrong answer. Questions f1 (a) (b) x? (c) (d) Does n (в€’ times ) = в€’ f ( by ) Will the inverse function exist for all those Is the function periodic? May be the function constant at x = 0? f2 Functions f3

Decide the velocity and acceleration of the particle for time big t. b. At what principles of capital t is the molecule at rest? c. At what values of t will the particle transform direction? g. What is the speed when the speed is first no? 1969 ABS 3 Presented f ( x) sama dengan

1969 ABS 6 A great arched window with foundation width 2b and elevation h is placed into a wall. The arch is to be either an arc of a allegoria or a half-cycle of a cosine curve. a. If the posture is a great arc of the parabola, create an formula for the parabola relative to the coordinate system demonstrated in the physique. (x-intercepts happen to be (в€’b, 0) and (b, 0). y-intercept is (0, h). ) b. In case the arch is actually a half-cycle of a cosine competition, write a great equation for the cosine curve relative to the coordinate system shown in the figure.
