For question 5 i dont understand how to solve a function. Can you please explain step by step on how to do it? Aswell as for the others

5. Each parabola in question 4 is defined by one of the functions below a) f(x) = x2 - 5x - 6 c) f(x) = -x+ 6x -10 b) f(x) = -x+8x+ 12 d) f(x) = x2 - 4x + 3 Identify the function that defines each graph. Then verify the coordinates of the vertex that you determined in question 4. 6. State whether each parabola has a minimum or maximum value, and then determine this value. c) a b) 2- 2 - 2 VX O -4 0 K -4 -2 2 4 O 10 20 -47 7. a) Complete the table of values shown for each of the following functions. i ) y= x2 + 5 ii) y = - 2 2 b) Graph the points in your table of values. c) State the domain and range of the function
