I need help with part a to this question

x : __ - 2 __ -1 ___0 ___ 1 ___ 2 ___ 3

y: ___ 5___ 2___ 1 ___ 25 ___ - 3

Step-by-step explanation:

Table of values for part A

Equation : y = x² + 1

x : __ - 2 __ -1 ___0 ___ 1 ___ 2 ___ 3

y: ___ ___ 1 __ ___5 __ - 3

Substitute the value of x to obtain the missing values _

x = - 2

y = (-2)² + 1 = 4 + 1 = 5

x = - 1

y = (-1)² + 1 = 1 + 1 = 2

x = 1

y = (1)² + 1 = 1 + 1 = 2

answer: .75 km

step-by-step explanation:

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
