Step-by-step explanation:
Given equation is representing the graph of parabola which opens down and its pick is its vertex
The vertex is calculated by vertex formula:
x = -b/2a for the equation y = ax² + bx + cIn our case t is the vertex and its value is:
t = -42/(-1.5*2) = 42/3 = 14 secondsОтвет:
false
