7.] Consider the following 2 statements: 1. sin (x + E) is sin[x] shifted E to the left I]. -cos(x) is cos[x] rotated around the x-axis Which of the following is correct? [a] Only I is true for all x [h] Only [I is true for all x [c] Both I and II are true for all x [d] Neither I or II is true for all x 8.] Suppose f[x] is a differentiable function and we know that f(3) : 3 and f'(3) : 1. Use local linear approximation to estimate the value for f(3.5). [a] 2.5 [b] 2.25 (c) 3.25 (d) 3.5
