What is the y-intercept of the function f (x) = 2x+12

answer is f (0) = 12

Step-by-step explanation:

f (x) = 2x + 12

to find y-intercept, subsitute x=0

f (0) = 2 x 0 + 12

any expression multiplied by 0 equals 0

f (0) = 0=12

when adding or subtracting the quantity does not chnage

f (0) = 12
