8. Select all functions that are one-to-one (i. e., have an inverse that is also a function) for all values of x.
A. f(x) = log2 *
B. f(x) = Vx - 3 C. y = x - 51
D. f(x) = 3x - 1
E. f(x) = x2 + 2x - 5 F. f(x) = x3 - 2x + 64
-2-

the answer is b.)

< 1=< 2

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
