Answer:
Step-by-step explanation:
Given equation is representing the graph of parabola which opens down and its pick is its vertex
<u>The vertex is calculated by vertex formula:</u>
- x = -b/2a for the equation y = ax² + bx + c
<u>In our case t is the vertex and its value is:</u>
- t = -42/(-1.5*2) = 42/3 = 14 seconds
16 Pints
if that's what your asking
g(x)=-2
Simplfy: y=-2
x=-9
*Look at where the points intersect
Answer: A and C And B
Step-by-step explanation: (I AM NOT 100% SURE WAIT FOR SOME ELSE JUST IN CASE if you dont uh hope its right)
14 because u are adding both factor and u are adding
