Answer:
5m² - 6m + 1
Step-by-step explanation:
f(x) = 5x² + 4x - 5
substituting value,
f(m-1) = 5(m-1)² + 4(m-1) - 5
so,
5(m-1)² + 4(m-1) - 5
= 5(m²-2m+1) + 4m -1 - 5
= 5m² - 10m + 5 + 4m - 4
= 5m² - 6m + 1
Answer:

Step-by-step explanation:
General equation of a parabola that opens up is
, a>0
So equation becomes
which implies option A and option B can never be true for this parabola.
Also this parabola's vertex lies in 3rd quadrant where coordinates of both x and y will be negative.
So, the equation of parabola will be of the form 
Hence, option 4 that is
is correct.
Y = kx (from definition of "varies directly")
if you know x, find k, then you will find y
Answer: 8% is correct!
