Answer:
x=12615.4019
Step-by-step explanation:
16856.70x=1.3362
So: x = 16856.7/1.3362
x=12615.4019
Answer:
(-∞, -2]
Step-by-step explanation:
Domain of a function is defined by the x-values (Input values) and y-values define It's range.
From the graph of a parabola,
Graph shows the increase in the value from x = -∞ to x = -2 then the values are decreased from x = -2 to ∞.
Therefore, domain in which the function is increasing : (-∞ , -2]
