The value of K is 5 because its going up 5 from the f(x) graph
Answer:
The y-intercept is 3000. The slope is -275. Therefore, your equation in slope intercept form is y = -275x +3000.
Step-by-step explanation:
Y intercept is found where x = 0 or on the y axis, so the only place on this graph where x = 0 and there is a number on the y axis is at (0, 3000), making 3000 your y intercept. The slope is figured from two points, and taking y2-y1/x2-x1. This would give you 3000-2450/2-0 which is -550/2 which is -275. That's your slope. Slope intercept form is y = mx+b, where m is the slope and b is the y intercept. Just plug in, and you get y = -275x+3000

Exercise 1:
The exponents are wrong: when you divide two power, you subtract the exponents:
Exercise 2:
The function represents a growth rate of 300%! 3% is actually written as 0.03, so the correct function is
Exercise 3:
To factor a quadratic equation, we have to find the roots. Once you have the roots 
, you can factor the expression as 
In this case, the solutions are 
, which yields the factorization
Exercise 4:
When you multiply two powers of the same base, you add the exponents:
So, in your case, you have
X^4 - 3x^2 + 2 = 0
(x^2 - 2)(x^2 - 1) = 0
so either x^2 - 2 = 0 or x^2 - 1 = 0
so x^2 = 2 or x^2 = 1
so x = sqrt 2 , - sqrt2, 1 , -1 Answer
all the roots are real
