Evaluate the function at the indicated values if answer is undefined enter undefined
F(x)=1-3x/8,f(3),f(-3),f(1/3),f(a),f(-a),f(a-1)
F(3)=
F(3)=1-3(3)/8
F(3)=1-9/8
F(3)=-1/8
To evaluate the function F(x) at the given values, we substitute the value of x into the function expression.
Given F(x) = 1 - (3x/8), we can start by evaluating F(3):
F(3) = 1 - (3(3)/8)
= 1 - (9/8)
= 1 - 1.125
= -0.125
So, F(3) = -0.125.
Moving on to the next values:
F(-3) = 1 - (3(-3)/8)
= 1 + 9/8
= 1 + 1.125
= 2.125
F(1/3) = 1 - (3(1/3)/8)
= 1 - (1/8)
= 1 - 0.125
= 0.875
F(a) = 1 - (3a/8)
= (8 - 3a)/8
F(-a) = 1 - (3(-a)/8)
= (8 + 3a)/8
F(a-1) = 1 - (3(a-1)/8)
= (8 - 3a + 3)/8
= (11 - 3a)/8
So, the function cannot be evaluated at a and -a. The expressions for F(a), F(-a), and F(a-1) are given as (8 - 3a)/8, (8 + 3a)/8, and (11 - 3a)/8 respectively.
