On a coordinate plane, solid circles appear at points (negative 7, 1), (negative 6, 4), (negative 2, 8.5), (negative 1, 7.75), (1, 4), (2, 1). A curved line connects these points in an arc. Use the graph to determine the input values that correspond with f(x) = 1.

x = 4
x = 1 and x = 4
x = −7 and x = 4
x = −7 and x = 2

x=-7 and x=2

Step-by-step explanation:

lol i just got it right laughing crying emoji

x = -7 and x = 2 :)

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
