Question

If f(x)=3x+8/2x-Aand f(0)=2.what is the value of a?

Answer 1

Answer:

$a=-4$

Step-by-step explanation:

Since $f(x)=\frac{3x+8}{2x-a}$, we have

$2=f(0)=\frac{3(0)+8}{2(0)-a}=-\frac8a$

Taking the reciprocal gives

$-\frac a8=\frac12$

Then multiplying by $-8$ gives

$a=\frac12(-8)=-4$
