The <em>correct answers</em> are:
C) No: we would need to know if the vertex is a minimum or a maximum; and
C)( 0.25, 5.875).
Explanation:
The domain of any quadratic function is all real numbers.
The range, however, would depend on whether the quadratic was open upward or downward. If the vertex is a maximum, then the quadratic opens down and the range is all values of y less than or equal to the y-coordinate of the vertex.
If the vertex is a minimum, then the quadratic opens up and the range is all values of y greater than or equal to the y-coordinate of the vertex.
There is no way to identify from the coordinates of the vertex whether it is a maximum or a minimum, so we cannot tell what the range is.
The graph of the quadratic function is shown in the attachment. Tracing it, the vertex is at approximately (0.25, 0.5875).
Answer:
(3) Jonah's graph has a steeper slope than Rowan's
Step-by-step explanation:
First we are going to write the equations for the amount of money that each one save
y = a+bx
Where y: Amount of money in the jar
a: Initial saving
b: Money saved every week ( graph's slope )
x: Number of week
Then, for Rowan
y = 50 + 5x
and for Jonah
y = 10 + 15x
Initially Rowan's graph lies above Jonah's graph but this situation change with time.
It is always true that Jonah's graph has a steeper slope than Rowan's, because for Rowan's graph the slope is 5 and for Jonah's graph the slope is 15
Then the answer is:
(3) Jonah's graph has a steeper slope than Rowan's
Answer:
x= 1,2,3,4,5,6,7,8,9,10 so simpal
Answer:
When rounding to the nearest half, round the fraction to whichever half the fraction is closest to on the number line. If a fraction is equally close to two different halves, round the fraction up but
