Question

Найти f(3)+f(1) если f(x)=x^2+x^3

Answer 1

F(x)=x²+x³

f(3)=3²+3³=9+27=36
f(1)=1²+1³=2

f(3)+f(1)=36+2=38

Answer 2

To find the value of f(3) + f(1), we first need to evaluate the function f(x) = x^2 + x^3 at x = 3 and x = 1, and then add the results.

Step 1: Calculate f(3) f(3) = 3^2 + 3^3 f(3) = 9 + 27 f(3) = 36

Step 2: Calculate f(1) f(1) = 1^2 + 1^3 f(1) = 1 + 1 f(1) = 2

Step 3: Add the results f(3) + f(1) = 36 + 2 f(3) + f(1) = 38

So, f(3) + f(1) is equal to 38.
