(5x-9)(5x²-3x+2)

2(5x-9)+2(5x²-3x+2)

(5x-9)(5x²-3x+2)

(5x²-3x+2) / (5x-9)

(25x³-60x²+37x-18) + (4x²-12x+9)

(25x³-60x²+37x-18) - (4x²-12x+9)

(4x²-12x+9) - (25x³-60x²+37x-18)

(2x-3)(25x³-60x²+37x-18)

the x's and y's are switched

the x's and y's are divided by 2

the x's and y's are made negative

the x's and y's are the same

no,

yes

f ^-1(x) = 3x + 5

f ^-1(x) = 3x - 5

f ^-1(x) = 3x - 15

f ^-1(x) = 3x + 15

f^-1(x) = 4x - 3

f^-1(x) = -1/4x - 3

f^-1(x) = 1/4x + 3

f^-1(x) = -4x - 3

Good

Ok, I need to study a little

Kind of iffy, I will be studying

I have no idea what's going on in this class
