Question

If, for a certain function, f(x)= 51, calculate the following values.

a.
f(x)-8

b.
1/2f(x)

c.
1/2f(x)-8

Answer 1

Answer: (a) 43 (b) 25.5 (c) 17.5

Explanation:

f(x) = 51

Replace f(x) with 51

a) f(x) - 8 = 51 - 8 = 43

`b)\quad (1)/(2)f(x)\qquad =(1)/(2)\cdot 51\qquad =(51)/(2)\qquad =25.5`

`c)\quad (1)/(2)f(x)-8\qquad =25.5-8\qquad =17.5`
