Let f(x)=151+4e−0.2x . What is the y-intercept of the graph of f(x) ? Enter your answer in the box.
+219 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
