How do you “multiply a by 2, then add b to the result”?

2 a + b

Step-by-step explanation:

Multiply a times 2 = a * 2 = 2 a

Then add "b" to the result we just obtained:

2 a + b

squares, rhombus, rectangles

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
