Answer:
Given Exponential Function is :
We have check which graph represent given Exponential Function,
let, 
Put x = 0, we get
y = 5 × 1 - 1 = 4
One of the passing through point = ( 0 , 4 )
Now, Put y = 0, we get
x = -1.465
Another passing through point is ( -1.465 , 0 )
So, Clearly No Given Option in attached is correct.
Correct Graph is attached.
Two ways:
1) guess factors(trial and error)
2) use quadratic formula.
If you use this method then a = -3, b = -6 and c = -1
x = -b +/- [sqrt(b^2 -4ac)/2a]
substituting a, b, and c into our equation we get:
x = - (-6)+/- [sqrt ((-6)^2) - 4(-3)(-1))/2 (-3)]
x = + 6 +/- [sqrt (36 -4 (3)/-6)] if I didnt make a mistake in my signs
x = + 6 +/- [sqrt (36 -12)/-6)]
x = 6 +/- [sqrt (24)/-6] but sqrt 6 x sqrt of 4 = sqrt 24 hence
x = 6 +/- [ sqrt 6 x sqrt 4 /-6] that is:
x = 6 +/- [sqrt 6 x 2 /-6 ]
so x = 6 + [sqrt 6 x 2/-6] and x = 6 - [sqrt 6 x 2/-6]
The answer is A!! hope i helped
Answer: 20% is your answer
Step-by-step explanation:
180-150=30
30 divided by 150 = .2 which is 20%
