Que. | If we define the functions f, g and h that map R into R by :
f(x) = x4, g(x) = √x2 + 1, h(x) = x2 + 72, then the value of the composite functions ho(gof) and (hog)of are given as |

a. | x^8 - 71 and x^8 - 71 |

b. | x^8 - 73 and x^8 - 73 |

c. | x^8 + 71 and x^8 + 71 |

d. | x^8 + 73 and x^8 + 73 |

Answer:x^8 + 73 and x^8 + 73 |
