Need help with these PreCal prac. questions

Question 1 Given the function: / (X ) = - 1. Identify the x and y - intercepts. No x intercepts, y-intercept at (0,-1) x intercept at (-1,0), no y- intercept O x intercept at (0,0), y intercept at (0,-1) O x intercepts at (1/3, 0) and (-1/3, 0) . y-intercept at (0,-1)\fQuestion 3 Given the function f (@) = -2 - 6x - 8, identify the x and y intercepts. O x intercepts: (-4,0) and (-2, 0) y intercept: (0,-8) O) x intercepts: (4, 0) and (2, 0) y intercepts: (0,0) and (0, -8) O x intercepts : (4, 0) and (2, 0) y intercept : (0, -8) O x intercepts: (0,-8) y intercepts: (-4,0) and (-2, 0)Question 4 Given the function / (@) = Gas - 2x - 3. Identify the axis of symmetry. Oy=0 Ox=3 O X =-1/3 OX=-3Question 5 Given the function / (@)= (@-2) + 6, determine the axis of symmetry. O X =-6 O x =-1/12 Ox =2 Ox =-2
