Find horizontal asymptote of y = 6024 + 7723 -23 20x4 + 23x2 + 14x + 15 Note: Give the exact answer but not the decimal approximation(for example, write 4/5 istead of 0.8). 52e 397 + 36e -44x Find the horizontal asymptotes of the curve y = 19e39x - 15e-44x Note: Give the exact answer but not the decimal approximation(for example, write 4/5 istead of 0.8). Answer: The equation of the horizontal asymptote which is above the x-axis is y = The equation of the horizontal asymptote which is below the x-axis is y = 12 - 25 Find the vertical asymptote of y = x2 - 25x + 100 Note: Give the exact answer but not the decimal approximation(for example, write 4/5 istead of 0.8). Find the vertical asymptote of the curve y 30e 121 + 130e-681 12e121 - 5e-68x Note: Give the exact answer but not the decimal approximation(for example, write 4/5 istead of 0.8). Write In for natural logarithm not log_e. also remember to put brackets, for example, write In(1/2) not In 1/2 Answer: The vertical asymptote is Find the values of c and d that makes the following function continuous on IR c+ d X- -64 if 8 cr + d if x = 8 Note: Give the exact answer but not the decimal approximation(for example, write 4/5 istead of 0.8) Answer:. The values of c and d are d =
