The graph of the equation y=f(x) passes through the points (-3,-5), (-2,-3),(0,1) and (4,9). What is the value of y in the equation y=f(-3)

Respuesta :

sqdancefan

Answer:

-5

Explanation:

Each ordered pair is a list of an x-vaue and the corresponding f(x) value.

Hence the first ordered pair listed, (-3, -5), means that when x = -3, f(x) = -5. In other words, f(-3) = -5. By the transitive property of equality,

... y = f(-3) = -5

means

... y = -5
