Evaluate the equation

53

Step-by-step explanation:

Let x = 1, 2, 3, 4, and add the values.

3 + (1^2 + 2 * 1) + (2^2 + 2 * 2) + (3^2 + 2 * 3) + (4^2 + 2 * 4) =

= 3 + 3 + 8 + 15 + 24

= 53

b and c

step-by-step explanation:

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
