Question

Luna graphed the function f(x) = 4x-3.2 on the X, Y coordinate plane. What is the y-intercept of the function?

A) -3.2
B) 0.8
C) 3.2
D) 4

Answer 1

The y-intercept of the function f(x) = 4x - 3.2 is -3.2.

Step-by-step explanation:

The y-intercept of a function is the value of y when x is equal to 0. In the given function f(x) = 4x - 3.2, we can find the y-intercept by substituting x = 0 into the function.

f(0) = 4(0) - 3.2

f(0) = -3.2

Therefore, the y-intercept of the function is -3.2.
