For each function, find f(−2),f(−0.5),and f(3).
f(x)=3/8 x−3
To find f(-2), f(-0.5), and f(3), we substitute the given values of x into the function f(x) = (3/8)x - 3.
f(-2) = (3/8)(-2) - 3 = -6/8 - 24/8 = -30/8 = -15/4
f(-0.5) = (3/8)(-0.5) - 3 = -3/16 - 48/16 = -51/16
f(3) = (3/8)(3) - 3 = 9/8 - 24/8 = -15/8
