Answer:
C)
Step-by-step explanation:
<h3>option—B&D</h3>we eliminate these two options
because remember quadratic function standard form
recall that, if
- a is negative then the graph will flip upside down
but a is positive so it won't flip upside down therefore,
these two are our answer
<h3>option-A:</h3>it seems good but it's not the answer according to the given condition however it's true for the opposite of the given condition:
<h3>option-C:</h3>it's our answer since the condition <u>x<</u><u>-</u><u>2</u><u> </u>for the quadratic function tells us everything is input For x which is less than -2 the graph-c as well yields so
likewise the absolute value function. the condition tells everything is input for x which is greater than or equal to -2 the graph also says so
hence our answer is C

Given :
Peter velocity , P = 30 mph .
Mitchell velocity , M = 40 mph .
Mitchell leaves 15 min later .
To Find :
If they drive along the same route how long will it take Mitchell to catch Peter.
Solution :
Distance covered by Peter in 15 min .
Let , time taken is x .
So , distance covered b them is equal :
Therefore , time taken by them is 45 minutes .
Hence , this is the required solution .
