Step-by-step explanation:

Second One :

+ = 900 + 1600 = √2500 = 50

Third One:

+ = 576 + 1024 = √1600 = 40

Fourth One:

+ = 2304 + 3025 = √5329 = 73

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
