Functions again for reference. f(x)=x+5 g(x) = 2 +6z+5 h(x)=2x-3 j(x) = -4x . . . Using the same functions given above, find (h-f)(z). (h-f)(z)=2x-3 x+5 (h-f)(x)=2x-3--5 Distribute the subtraction to each term. (h-f)(z) = 2x 3- 5 Rearrange to prepare to combine like terms. (h-f)(x): 18 Now, let's try another. Find m(a) = (g-j)(z) m(x)= x +6x+5-(8 Evaluate m(3) Write the functions, subtracting in the order given. m(x)=x + 6x +5+ adding a positive. We'll rewrite with this in mind.) m(x) = 2 +1 m(3) m(3) = 44 = Combine like terms and make sure new function is in standard form. (3)2 + 10(3) +5 Write the functions, subtracting in the order given Distribute the subtraction to each term. (Hint: Subtracting a negative is the same as +5 Combine like terms and make sure new function is in standard form. Functions again for reference. f(x)=x+5 g(x) = 2 +6z+5 h(x)=2x-3 j(x) = -4x . . .
