Evaluate the function for the given values of a and b. Then use the intermediate value theorem to determine which of the statements below is true.a = 1 and b = 2f(x) = 10x5 - 8x3 - 9x2 - 10
A. f(1 ) and f(2) have opposite signs, therefore the function f does not have a real zero between 1 and 2. B. f(1 ) and f(2) have the same sign, therefore the function f has a real zero between 1 and 2. C. f(1 ) and f(2) have the same sign, therefore the intermediate value theorem cannot be used to determine whether f has a real zero between 1 and 2. D. f(1 ) and f(2) have opposite signs, therefore the function f has a real zero between 1 and 2.
Use the Binomial Theorem to expand the binomial and express the result in simplified form.(x5 + 4y)4
A. x9 + 16x8y +24x7y2 + 16x5y3 + 4y4 B. x20 + 16x15y + 96x10y2 + 256x5y3 + 256y4 C. x20 + 12x15y + 96x10y2 + 192x5y3 + 256y4 D. x9 + 12x8y + 96x7y2 + 192x5y3 + 256y4
