use the function rule f (x) = 3x - 2 find the output f (1.5)
a. 2.5
b. -2.5
c. 6.5
d. -6.5
To find the output f(1.5) using the function rule f(x) = 3x - 2, you need to substitute x with the given value, which is 1.5.
So, calculate f(1.5) as follows:
f(1.5) = 3 * 1.5 - 2
= 4.5 - 2
= 2.5
Therefore, the output f(1.5) is 2.5.
Therefore, the correct option is:
a. 2.5
