Question

F(×) = 5(2) × +3 f(4)

Answer 1

120 f^2

OR

240f

Step-by-step explanation:

• Multiply f and f to get f 2.
• Multiply 5 and 2 to get 10.
• Multiply 10 and 3 to get 30.
• Multiply 30 and 4 to get 120.
• f^2 ×120

Answer 2

43

Step-by-step explanation:

Given the expression

f(x) = 5(2)x + 3

To get f(4), substitute x = 4 into the equation;

f(4) = 5(2)(4) + 3

f(4) = 10(4) + 3

f(4) = 40+3

f(4) = 43

Hence the value of f(4) is 43
