Question

What is the y-intercept of the function f(t)=1.90−1.40t?

A) 1.40
B) −1.40
C) 1.90
D) −1.90

Answer 1

The y-intercept of the function f(t) = 1.90 - 1.40t is 1.90, which is option C.

Step-by-step explanation:

The y-intercept of a function is the value where the function crosses the y-axis. In the function f(t) = 1.90 - 1.40t, the y-intercept is the value of f(t) when t is 0. Plugging t = 0 into the equation, we get f(0) = 1.90. Therefore, the y-intercept of this function is 1.90, which corresponds to option C) 1.90.
