On a Physical Science exam, students earn 3 points for a correct response, 1 point for a partially correct response, and 0 points for an incorrect response. Suppose a student
had 8 partially correct responses and 4 incorrect responses and received a total of
77 points on the exam. Write an equation that can be used to solve for the number of
correct responses the student had. Use c to represent correct responses.

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

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.
