For the function y = x + 4, what is the output value if 3 is the input value? options
1.y=1
2.y=34
3.y=7
4.y=12

you can't solve x because it is 2 linear equation and you only have one equation

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
