Answer:
The V-shaped graph opens downward, and its vertex lies at (1, 12).
Step-by-step explanation:
- first, plot the graph of f(x),
- take some 5 random negative and positive x values and then find corresponding f[x] values.plot f(x) on y-axis. now, plot these points on the graph and finally join all the points. this gives u the required graph.
- I have plotted the graph and uploaded it.
refer it.
- by seeing the graph, we can easily say that,The V-shaped graph opens downward, and its vertex lies at (1, 12).

Answer:
<h2>The probability is 58 %.</h2>Step-by-step explanation:
This problem belong to a normal distribution probability.
Mean = 63.6
Standard Deviation = 2.5.
We have to find the probability of a height greater than 63.0.
Due to the normal probability, we need to find the Z score first:
; where x is the height, u is the mean, and o is the standard deviation.
Once we have our Z score, we find the probability with the z-table (attached). So, for a z score of -0.24 we have a probability of 0.42.
But, the problem is asking for height greater than 63.0, this mean that we have to subtract 0.42 from 1, giving as result 0.58, which means a 58% of probability,
