Question 7 Find the function composition (f o g) (x) and its domain. Let f (x) = Vx and g (x) = x - 3. O (f o g) (x) = Vx - 3 with domain: [3, co) O (f o g) (x) = VI - 3 with domain: (-00, co) O (f o g) (x) = VI - 3 with domain: (-3, co) O (f o g) (x) = VI - 3 with domain: [0, co) D Question 8 10 pts Find the equation of a line that is perpendicular to the line 2x - 3y = 1 and passes through the point (-4, 8). Give your answer in the form y = mx +b. O y = bit: Oy= - 3x- Oy = - zi+3 O y = - 31+2
