Write the quadratic equation whose roots are 1 and -3, and whose leading coefficient is 4. (Use the letter x to represent the variable.)

x

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
