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.
Answer:(4) right angle
Step-by-step explanation:
you need to get 180 right solve it from there
Answer:
105 degrees
Step-by-step explanation:
Angle DEF measures 75°.Triangle DEF is an isosceles, so AngleDEF Is-congruent-toAngleDFE.
the angles all together is 180 degrees
so 180 - 75 = 105 degrees
9x5=45 the building would be 45 feet tall
Answer:
g= - 32
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Flip the equation.
Step 3: Add 5 to both sides.
Step 4: Multiply both sides by 4/(-1).
g=−32
