Given f(x) = x 3 + x 2 x, what is f(4)?

Answer 1

Hi Jesus,

I think your sum should be written like this f(x) = x^{2 +} x^{3 ,} then what is f(4) ?.........(1)

Because I hope its not the coefficient of X , then you would write before X like 3x or 2x....

substituting the value 4 in x in the given function of x we get .. 4² + 4³ = 16+ 64 = 80

Answer 2

By the way your question is typed, it's difficult to understand the format. Are the numbers in the problem exponents or coefficients? If it's an exponent, type it with a caret as follows:

x squared = x^2

If it's a coefficient, it goes before the number as follows

3x

For now, I can only help by saying that to solve this problem, substitute the number 4 for each x in the problem.
