f(x)=151+4e−0.2x

 

To find the y-intercept we start off with that the x-intercept is 0 so x = 0

y = 151 + 4e - 0.2 * 0

y = 151 + 4e - 0

 

put like terms next to each other in order to subtract them

y = 4e + 151 - 0

y = 4e + 151 

 

Since you cannot go further with this equation this is your y-intercept

 

(0, 4e + 151)

 

Hope this helps ;P
