Step-by-step explanation:
A quadratic equation may be expressed as a product of the two binomials. The roots of the equations are 3 and 10, so the factors are (x-3) and (x-10).
f(x) = (x-3)(x-10)
f(x) = x^2 - 13x + 30
Domain: (2,3]
Range: (5,-2]
Answer:
subtract 5 from each side z=2
Step-by-step explanation:
Let the two integers be x and y respectively
Hence;

From the first equation ;

Substitute into the third equation

Open up the bracket

Take everything to the right hand side of the equation and you'll have a quadratic equation

Solve the quadratic equation and you'll have two roots

Substitute for each value of y in the first equation
Therefore:




Therefore the answer is A
