Final answer:
The quadratic equation that has its axis of symmetry at x=1.5 must have its coefficients a and b satisfy the condition x = -b/2a = 1.5. Without specific equations, we cannot provide a particular example, but any quadratic following this condition would suffice.
Step-by-step explanation:
The question asks for an equation of a parabola that has its axis of symmetry at x=1.5. The axis of symmetry of a parabola described by a quadratic equation in the form y = ax^2 + bx + c is given by the formula x = -b/2a. To have an axis of symmetry at x=1.5, the values of a and b must satisfy the condition x = -b/2a = 1.5. Without specific equations provided in the question, we look for any quadratic equation that can fit this criterion. More than 100 words would be necessary to elaborate on various quadratic equations and their corresponding axis of symmetry; however, as specific equations are not given in this question, this general explanation should suffice. One must remember that only a quadratic equation can have an axis of symmetry represented by a single vertical line, such as x=1.5.
