draw the graph that satisfies both conditions: domain is all real numbers and f(2)=-1

draw the graph that satisfies both conditions: domain is all real numbers and f(2)=-1
y=f(x)
in this the values which x can take is called domain
f(2)=-1
Now there can be infinite functions satisfying both
Ex: linear function
Y+1=0
This function domain is all real value and f(2) is...
