200 students appeared in an examination. If 25% of student passed the examination, find the number of student who failed in the examination a. 150
b. 100
c. 275
d. 175

​

150 students failed

25% of 200 is 50 therefore 200-50 (50 being the amount of students passed) would be 150

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
