Write the quadratic function in standard form. y = (x + 1)^2– 8

y = x² + 2x - 7

Step-by-step explanation:

The standard form of a quadratic is y = ax² + bx + c : a ≠ 0

Given

y = (x + 1)² - 8 ← expand factor using FOIL

  = x² + 2x + 1 - 8

  = x² + 2x - 7 ← in standard form

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.

yes   because as the functions are graphed they eventually will intersect unless otherwise
