Given the function f defined by the formula f(x)=2x+1 find the following
a. f(4) b. f(-5) c. f(0) d. f(1/2)
show your work

The function f defined by the formula f(x) = 2x +1 can be expressed as: f(4) = 9; f(-5) = - 9, f(0) = 1,

The function of a function defines and explains the relationship between two different variables. From the given information, we are meant to replace x with the following given options and solve for the value of x.

f(4) = 2(4) + 1

f(4) = 8 + 1

f(4) = 9

f(-5) = 2(-5) + 1

f(-5) = -10 + 1

f(-5) = - 9

f(0) = 2(0) + 1

f(0) = 0 + 1

f(0) = 1
