Answer:
[tex]1.9[/tex]
the cost of the hamburger will be [tex]\$1.9[/tex] if no toppings are added.
Step-by-step explanation:
The function is
[tex]f(t)=1.9+1.4t[/tex]
Let cost of toppings be [tex]y[/tex]
[tex]y=1.9+1.4t[/tex]
The y-intercept of a function is the value of the function when [tex]x=0[/tex]. Here number of toppings [tex]t=0[/tex].
So, the intercept of the function is [tex]1.9[/tex]
This means the cost of the hamburger will be [tex]\$1.9[/tex] if no toppings are added.
