The graphs below have the same shapes. What is the equation for the red graph?
1 answer:
The equation of the red graphed function is: g(x) = 1 - x².
<h3>How to Find the Equation of a Graphed Function?</h3>Given the graph shown in the attachment below, the graphed function heads downwards, and the x - axis is intercepted at ( 1, 0 ) and (-1,0).
Thus, the x-intercepts, which is the zeros of the function, are: 1 and -1.
So, g(x) = (x + 1)(x -1)
Expand:
g(x) = 1 - x²
The equation of the red graph is: g(x) = 1 - x².

Step-by-step explanation:
<u>Use the Binomial Theorem</u>
We have the probability of success, , and the probability of failure,
. The binomial coefficient,
, represents the amount of possible combinations that
items can be chosen out of
items, with its respective formula
.
Hence, the best choice for the probability that 4 students chosen at random from the class of 30 that want the next test to be on Monday will be option B, 0.02
