Suppose we have function defined by :
f(x)= -3x+7
what values of x give f(x) =-17?
1 answer:
Answer:
x = 8
Step-by-step explanation:
if f(x) = -17
then we can type:
- 3 x + 7 = -17
solving for "x", subtract 7 from both sides
- 3 x = - 17 - 7
- 3 x = - 24
divide both sides by -3 to isolate "x"
x = -24 / (-3)
x = 8
