Final answer:
The equation y=4.9x^2+10x+24 is not proportional because it is a quadratic equation representing a curvilinear relationship, not a direct linear relationship with a constant rate of change.
Step-by-step explanation:
You asked if y=4.9x^2+10x+24 is proportional. To determine if an equation is proportional, we look for a direct linear relationship where the equation can be expressed in the form y = mx, where m is the constant of proportionality. Since the equation given is a quadratic equation (evidenced by the x^2 term), it represents a curvilinear relationship between y and x. Therefore, y is not directly proportional to x because it does not have a constant rate of change and includes an x^2 term and an additional linear term 10x.
