\( f(x)=\frac{1-x}{1+x} \), then the value of \( f\left(f\left(\frac{1}{x}\right)(x=0)\right. \) is (A) \( x \) (B) 0 (C) \( \frac{1}{x} \) (D) \( x^{2} \) (E) 1

Graph each relation. Find the domaln and range. \( \begin{array}{ll}\text { 62. }\{(0,1),(1,-3),(-2,-3),(3,-3)\} & \text { 63. }\{(4,0),(7,0),(4,-1),(7,-1)\} \\ \text { 64. }\{(1,-2),(2,-1),(4,1),(5,2)\} & \text { 65. }\{(1,7),(2,8),(3,9),(4,10)\}\end{array} \)

Use the distributive property to fill in the blanks below. \[ 7 \times(9+5)=(7 \times \square)+(7 \times \square) \]

Which of the following is a rational number? Enter your answer(s) separated by commas \[ \begin{array}{r}\sqrt{2} \\ 0.7878878887 \ldots \\ 1 \\ \frac{10}{19}\end{array} \] \( 0.7070070007 \ldots \)

Find the \( 5^{\text {th }} \) root of \( \frac{1024}{3125} \)

If we add two irrational numbers the resulting number is? Select one: Always an rational number Always an integer Always an irrational number May be rational or irrational number
