**helper**, Wednesday, January 19, 2011 at 10:04pmjust plug in the values for x and solve

f(x) = x^2 + 3

f(2) = 2^2 + 3

f(2) = ?

f(x) = x^2 + 3

f(5) = 5^2 + 3

f(5) = ?

**Esther**, Wednesday, January 19, 2011 at 10:10pmPlease forgive me, math is not my forte as you can see. Does that mean that f(5)= 5? and f(2)= 2? Thus, the answer is (5,2)or just 5 and 2? I guess what I'm trying to determing is how do you write the answer? Thank you and pleae excuse my confusion.

**helper**, Wednesday, January 19, 2011 at 10:17pmf(x) = x^2 + 3

f(2) = 2^2 + 3

f(2) = ?

2^2 = 4

f(2) = 2^2 + 3

f(2) = 4 + 3

f(2) = 7

the answer for f(2) is 7

when x = 2, the function value = 7

now, you do the other one

**helper**, Wednesday, January 19, 2011 at 10:37pmNo, f(5) does not = 10

f(x) = x^2 + 3

f(5) = 5^2 + 3

f(5) = ?

5^2 = ?

5^2 + 3 = ?

show me how you got 10

**Esther**, Wednesday, January 19, 2011 at 10:40pmI added 5 and 2 + 3. I am obviously wrong. Sorry!

**Esther**, Wednesday, January 19, 2011 at 10:46pmI think the answer is 5 because of the polynomial 2, I could be wrong but doesn't that amount to 5 twos, in other words, 2,2,2,2,2, which equal 5, one whole number? Sorry, i'm lost.

**helper**, Wednesday, January 19, 2011 at 11:40pmf(x) = x^2 + 3

f(5) = 5^2 + 3

f(5) = ?

5^2 = 5 x 5 = 25

f(5) = 5^2 + 3

f(5) = 25 + 3

f(5) = 28

(Not a perfect square there because of the text size).

How many are in 5^2? (Just count them up. It is 5 up or 5 across in every row/column).
