Hey Banele, good to see you again.
a) To find the values of $a, b,$ and $c$ for $f(x) = ax^2 + bx + c$:
Step 1: Use the x-intercepts $(-1; 0)$ and $(7; 0)$ to write the function in factored form.
$$f(x) = a(x - x_1)(x - x_2)$$
$$f(x) = a(x - (-1))(x - 7)$$
$$f(x) = a(x + 1)(x - 7)$$
Step 2: Use the y-intercept $(0; 3.5)$ to find the value of $a$.
