Q:
# PLEASE PLEASE HELP ME?!?!!? PLEASSEE I ONLY HAVE 2 QUESTIONS!!!When the function f(x) = 6(9)x is changed to f(x) = 6(9)x + 1, what is the effect? Select one: a. There is no change to the graph because the exponential portion of the function remains the same. b. All input values are moved 1 space to the right. c. The x-intercept is 1 space higher. d. The y-intercept is 1 space higher.Evaluate fourth root of 9 multiplied by square root of 9 over the fourth root of 9 to the power of 5 . (5 points)Select one:a. 9 to the power of negative 1 over 2b. 9 to the power of negative 1 over 4c. 9d. 92

Accepted Solution

A:

Answer:d. The y-intercept is 1 space higher.a. 9 to the power of -1/2Step-by-step explanation:1. Changing f(x) to f(x) + 1 adds 1 to every output value of the function, moving that value "1 space higher". This is true for the y-intercept, too.___2. The rules of exponents apply:a^b Β· a^c = a^(b+c)1/a^b = a^-bYou apparently want to simplify ...... 9^(1/4) Γ 9^(1/2) / 9^(5/4)... = 9^(1/4 + 1/2 - 5/4)... = 9^((1+2-5)/4)... = 9^(-2/4) = 9^(-1/2)
