Answer:
Option (2). Increasing x > 0; decreasing x < 0
Step-by-step explanation:
Equation of the parabola having vertex (0, 3) will be,
y = (x - 0)² + 3
y = x² + 3
To check the function is increasing or decreasing in the given intervals we will find the derivative of the function,
y' = 2x
For x < 0 Or x = -1
y' = 2(-1)
= -2 < 0
Therefore, function is decreasing in x < 0
For x > 0 Or x = 1
y' = 2(1) + 3
= 5 > 0
Therefore, function is increasing in x > 0
Option (2) is the answer.
34.3 Km /h was her average velocity in km/h.
What is average velocity?
- The change in position or displacement (x) divided by the time intervals (t) during which the displacement happens is the definition of average velocity.
- Based on the direction of the displacement, the average velocity might either be positive or negative. Meters per second (m/s or ms-1) is the SI measure for average velocity.
- The displacement of a body, or the shortest distance it must go during a trip, is calculated as the displacement multiplied by the time interval over which it covered that distance.
average velocity = Displacement / time taken
V = d/ l
V = 10.3 Km/0.300m = 34.3Km

Answer:
constant term:n
numerical coefficient:2
Step-by-step explanation:
a numerical coefficient is a fixed number that is multiplied to a variable. So in the expression, the numerical coefficient would be 2
A constant term is something in an algebraic expression that does not change which is n
Answer: $255
Explanation: Multiply 300x15% to find the amount of money discounted which is $45. Then subtract the $45 from the $300 to get $255. Hope this helps!
