Given: f (-x) = x - 7 and h (x) = 2x + 3

Write the rule for f (h (x)).

O

f (h (x)) = 2x - 7

f (h (x)) = 2x - 4

f (h (x)) = 3x - 4

f (h (x)) = 3x - 7

    if given f (-x) = x-7, then f (h (x)) = -2x-10

    or if given f (x) = x-7, then f (h (x)) = 2x-4

    Step-by-step explanation:

    if given f (-x) = x-7

    f (-x) = x-7 = > f ( - (-x)) = (-x) - 7 = >f (x) = - x-7

    f (h (x)) = f (2x+3) = - (2x+3) - 7 = - 2x-3-7 = - 2x-10

    if given f (x) = x-7

    f (h (x)) = f (2x+3) = 2x+3-7=2x-4
