What is 10b +19 when b= -2

-1    i hope this helps!    :)

Step-by-step explanation:

you are given both 10b + 19    and b = -2

lets plug in the value of b

10b(-2) + 19

multiply the 10b and the -2

-20b + 19

-20 + 19 = -1

-1

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

the answer is 13/48
