Find the indicated function values for the function f(x) = 6x-7 a. f(0) b. f(3) c. f(-4) x-7 d. f(a + h) e. Why must 7 be excluded from the domain of f? a. f(0) = (Simplify your answer.) b. f(3)=(Simplify your answer.) c. f(-4)=(Simplify your answer.) d. f(a+h)=(Simplify your answer.) e. Why must 7 be excluded from the domain of f? OA. This value of x would make the numerator and denominator zero. OB. This value of x would make the denominator negative. OC. This value of x would make the denominator positive. OD. This value of x would make the denominator zero.
