First set everything to 0.
${x}^{2} + x - 5$
Giving you A= 1 , B= 1 and C= -5
Then input everything into the quadratic formula and either solve by hand or use a calculator.
Note exact values are found by hand, decimals are found using a calculator.

The graph below shows the distance in miles, m, hiked from a camp in h hours.

Artist 52 [7]

Answer:

Option 1) is correct

Step-by-step explanation:

Given: The graph shows the distance in miles, m, hiked from a camp in h hours.

To find: hourly interval that had the greatest rate of change

Solution:

Rate of change between two points refers to the vertical change divided by the horizontal change.

For hour 0 to hour 1:

rate of change = $\frac{2-0}{1-0}=2$

For hour 2 to hour 3:

rate of change = $\frac{4.5-3.5}{3-2}=1$

For hour 1 to hour 2:

rate of change = $\frac{3.5-2}{2-1}=1.5$

For hour 3 to hour 4:

rate of change = $\frac{5-4.5}{4-3}=0.5$

So, rate of change is greatest in interval: hour 0 to hour 1
