Question

Let f (x)= x² + 3x,
2
f (1)=

Answer 1

Answer: Therefore, f(1) is equal to 4 when the function f(x) = x^2 + 3x is evaluated at x = 1.

Step-by-step explanation: o find the value of f(1) for the given function f(x) = x^2 + 3x^2, we substitute x = 1 into the function. 1. Substitute x = 1: f(1) = (1)^2 + 3(1)^2 2. Simplify the expression: f(1) = 1 + 3 3. Perform the addition: f(1) = 4

Answer 2

Answer:4

Explanation:

If f (x)= x² + 3x, f(1)=1^2+3*1=4
