The function below shows the cost of a hamburger with different numbers of toppings (t). f(t) = 1.90 + 1.40t What is the y-intercept, and what does it mean?

the cost of the hamburger will be if no toppings are added.

Step-by-step explanation:

The function is

Let cost of toppings be

The y-intercept of a function is the value of the function when . Here number of toppings .

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
