Fluency Practice

Function A (algebraic): $f(x) = x^2 - 4$ .

Function B (table):

Which function has the larger $y$ -intercept?

Function A, with $y$ -intercept $-4$ .

Function B, with $y$ -intercept $-4$ .

They have equal $y$ -intercepts of $-4$ .

Function A, because $f(x) = x^2 - 4$ has a subtracted $4$ , making it larger.
