Question

F(×)=[2×
[1/2×+5/2
F(3)=

Answer 1

Step-by-step explanation:

The given expression is F(x) = [2x; 1/2x + 5/2].

To find F(3), we substitute 3 in place of x in the expression.

F(3) = [2(3); 1/2(3) + 5/2]

Simplifying,

F(3) = [6; 3/2 + 5/2]

Adding the fractions,

F(3) = [6; 8/2]

Simplifying the fraction,

F(3) = [6; 4]

Therefore, F(3) = [6; 4].

In this case, F(3) represents the value of the function F at x = 3. It means that when we substitute 3 for x in the expression [2x; 1/2x + 5/2], we get the result [6; 4]. The semicolon separates the two elements of the expression, where the first element corresponds to the first row and the second element corresponds to the second row.

Answer 2

If F(x) = 2x for the value x=3, then F(3) would be 2*3 = 6. If it's the second case, then it would be 1/2*3 + 5/2 which simplifies to 1.5 + 2.5 = 4.

Step-by-step explanation:

The function F(x) presented in the question appears to have typing errors, preventing a clear response. To find F(3), we need the precise definition of F(x).

A correct answer depends on the valid part of the function for x=3, and whether F(x) would be 2x or another expression for that region.

The given question seems to present a function F(x) which has different cases or parts, and then asks for the value of F(3).

To proceed correctly, we would need the precise definition of F(x).

Assuming that F(x) is defined piecewise and one piece is for example 2x and another might be 1/2x + 5/2, you would substitute x=3 into whichever part of the function is valid for x=3.

If F(x) = 2x for the value x=3, then F(3) would be 2*3 = 6. If it's the second case, then it would be 1/2*3 + 5/2 which simplifies to 1.5 + 2.5 = 4.
