CCSS.HSF.IF.C.7

Compare f(x) to g(x). Which statement is true about the vertex of these functions? (Remember, when a parabola is concave up, the vertex is a minimum).

• f(x) has a greater minimum than g(x).

• g(x) has a greater minimum than f(x).

CCSS.HSA.REI.D.10

• g(x) has a greater y-intercept of 12 compared to h(x) which is a -4.

• h(x) has a greater y-intercept of 7 compared to g(x) which is a -5.

• They have equal y-intercepts of 1.

• Trick question, we don't know the y-intercept since the equations are NOT in standard form.
