Three quadratic functions are being compared to determine which has the smallest y-intercept. the first quadratic function can be modeled by the equation a(x) = (x + 5)2 − 7. the second function, b(x), can be modeled by the values presented in the table. the third quadratic function, c(x), is graphed below. which quadratic function has the smallest y-intercept and what is this value? x b(x) −3 0 0 6 3 0 a(x) has the smallest y-intercept: −7. b(x) has the smallest y-intercept: −3. c(x) has the smallest y-intercept: −2. a(x) has the smallest y-intercept: −5.
