Question

If f(x)=2∣x∣+3x when x=1, what is the value of f(x)?

a) 5

b) 1

c) -1

d) 7

Answer 1

To find the value of the function f(x) at x = 1, we input x into the equation f(x) = 2|x| + 3x, which yields a result of 5. Therefore, the value of f(x) when x = 1 is 5.

Step-by-step explanation:

The question asks for the value of the function f(x) = 2|x| + 3x when x = 1. To find the value, we substitute x = 1 into the function:

• f(1) = 2|1| + 3(1)
• f(1) = 2(1) + 3(1)
• f(1) = 2 + 3
• f(1) = 5
• Hence, the value of f(x) when x = 1 is 5, which corresponds to option (a).
