Please help. Thanks! 10

Let f(x) = 5x - 2 and g(x) = 4x - 6. Write a formula for each of the following functions. f + g = f- g = g - f = g + f = fg = ff =

a) f+g= (5x-2)+(4x-6) = 5x-2+4x-6 = 9x-8

b) f-g =(5x-2)-(4x-6) = 5x-2 -4x+6 = x+4

c)g-f= (4x-6)-(5x-2) = 4x-6-5x+2 = -x-4

d) g+f = (4x-6)+(5x-2)= 4x-6+5x-2= 9x-8

e)fg= (5x-2)(4x-6)= 20x²-30x-8x+12 = 20x²-38x+12

f) ff = (5x-2)(5x-2)= 25x²-10x-10x+4 = 25x²-20x+4
