If x+y=10 and x-y=4, find the value of x2+y2

x+y+x-y=10+4

2x=14

x=7

7-y=4

y=11

put the value x and y of in x^2+y^2

16+121=137

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
