What is the value of the function f (x) = 2x+5 when x=3

a) 8

b) 11

c) 13

d) 28

b) 11

Step-by-step explanation:

step 1: f (3) = 2 (3) + 5

substitute (plug in) the value of x which in here is 3

step 2: 2 (3) = 6 + 5 = 11

follow order of operations

P - parenthesis

E - exponent

MD - multiply and divide from left to right

AS - add and subtract from left to right

f (x) = 2x+5

=2*3+5

=6+5

=11

=b
