ANSWER ALL QUESTIONS BELOW 1. Which is not true about the function of y = (x + 3)3(2x – 3)5? Select one: the first derivative of y is (x + 3)²(2x - 3)^(16x + 21) O b. the function can be expressed in logarithmic equation as In y = 3 ln(x + 3) +5 ln(2x - 3)5 O c. the function can be expressed in logarithmic equation as In y = ln(x + 3)3 + ln(2x – 3)5 O d. the second derivative of y is 2(x + 3)-2 + 8(2x – 3)-1 + 16(16x + 21)-1 Given sin(x + y) = x cos y. Use implicit differentiation to find the value of y' at point (30°,60°). Select one: 2 1573 1 1573 1/2 3073 1 303 O d.
