The answer is (it can be curved) because it's doesn't have to cross the origin and it's a U shape so it can't look like a straight line and it doesn't have a constant rate of change. :)
Second one, and can I have brainelist,please, and thanks
To effectively determine the correct answer, it would be helpful to write this into an algebraic expression. We let x as the number. We do as follows:
<span>Four times the square of a certain number increased by 6 times the number equals 108.
4x^2 + 6x = 108
The numbers can be either of the following since the equation generated was a quadratic equation which has two roots.
x = 4.5
x = -6 </span>
