What is the domain of the function f(x) = x2 + 3x + 5? a. all whole numbers b. all positive real numbers c. all integers d. all real numbers

The domain for this function is all real numbers (D).

The reason for this is that domain is equal to the numbers that you can put in for x. The only usual restrictions on this are 0 as a denominator and a negative under a square root symbol. Since we do not have fractions or square roots in this equation, the domain is all real numbers.

horizontal translation of 2 units in the positive x direction

followed by

vertical translation of 3 units in the positive y direction

i think that you should ask google for the answer to that problem because if we don't know it google does
