Answer: x=1.5
Step-by-step explanation: The equation is in In a standard form of equation as;
y = ax^2 + bx + c, and therefore, the axis of symmetry is given by the formula,
X = - b / 2a.
Therefore using that in the question, a = 1 and b= - 3.
Therefore, the axis of symmetry is:
x = - (-3) / 2(1) which gives
x = 3/2 or x=1.5
