Which of the following gives the correct intercept points and vertex point for the function ƒ(x) = x2 + 5x + 6? Question 1 options:

A)

y-intercept: (0,6); vertex point: (–5∕2, –1∕4); x-intercepts: (–2,0) and (–3,0)

B)

y-intercept: (0,–6); vertex point: (–7∕2, –1∕2); x-intercepts: (2,0) and (–3,0)

C)

y-intercept: (0,6); vertex point: (–5∕2, –5∕4); x-intercepts: (2,0) and (3,0)

D)

y-intercept: (0,–6); vertex point: (–5∕2, –1∕4); x-intercepts: (–2,0) and (3,0)

Rational numbers are numbers that can be written as a quotient of two integers:     a/b where a and b are both all integers can be expressed as fractions with 1 in the denominator. for example, 1 is 1/1, 2 is 2/1, -4 is the same as -4/1, and so on. so we can write all the integers as a  fraction with integer numbers in both the numerator and denominator. therefore, all integers are rational numbers.this statement is true.
