substitute x=17 into the function
f(17) = 2*17-3
f(17) = 34-3
f(17) = 31
Answer:
x = 4
Step-by-step explanation:
4(2x + 5) = 52 ( divide both sides by 4 )
2x + 5 = 13 ( subtract 5 from both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Answer:
the answer is 4/5
Step-by-step explanation:
Step-by-step explanation:
We can see that the function crosses the x-axis at 3 different places, we have x = 1, x = 4 and x = 6 as our roots.
(Note: x = 6 has a repeated root)
There could be complex roots if we know more about the function, but there must be 3 distinct roots.
The best answer here is option A.
