  • Substitute the value for x.
    f(−5) = 7 +|-5| = 7 + 5 = 12

  • Substitute the value for x.
    g(4)= 4³ − 5 = 64 − 5 = 59

  • Substitute the value for x.
    f(0) = 7 + |0| = 7 + 0 = 7

  • See parts (a) and (c).

  • Substitute the value for x.
    g(−2) = (−2)³ − 5 = −8 − 5 = −13

  • See parts (b) and (e).
