If f(x) = x2 + 2x, which expression represents f(x + 2)?

f(x) = x^2 + 2x

To get f(x + 2), we just plug in the x + 2 where ever there's an x

f(x + 2) = (x + 2)^2 + 2(x + 2)

f(x + 2) = x^2 + 4x + 4 + 2x + 4

f(x + 2) = x^2 + 6x + 8

x^2 + 6x + 8.

Step-by-step explanation:

We replace the x in f(x) by x + 2 then simplify.

f(x+2) = (x + 2)^2 + 2(x + 2)

= (x + 2)(x + 2) + 2(x + 2)

= (x + 2(x + 2 + 2)

= (x + 2(x + 4)

= x^2 + 6x + 8.

answer: d. $20

step-by-step explanation:

just took the test

we have the parent function given by,

1. the function is translated 5 units to the left.

so, we get,   becomes

2. the function is translated 5 units to the right.

so, we get,   becomes

3. the function is translated 5 units upwards.

so, we get,   becomes

4. the function is translated 5 units downwards.

so, we get,   becomes

5. the function is reflected across x-axis.

so, we get,   becomes

6. the function is reflected across y-axis.

so, we get,   becomes .
