Answer:
The y-intercept is -15.
Step-by-step explanation:
y - 5 = 5(x - 4) is our equation in point-slope form.
point slope form is = y - y1 = m( x - x1)
So, we know that the slope is 5 and one point is (4, 5)
We can use this point and the slope to find the y -intercept.
y = mx + b is slope intercept form.
Let's input the values we know to find the y-intercept.
5 = 5(4) + b
5 = 20 + b
-15 = b
The y-intercept is -15.
Answer:
(a) Growth
Step-by-step explanation:
Given
-- current
--- rate
Solving (a): Growth or decay
The question says his followers increases each day by 24%.
Increment means growth.
<em />
<em>Hence, it is a growth problem</em>
Solving (b): Equation to represent the scenario.
Since the rate represents growth, the equation is:
Substitute: and
Answer:
f(x) = 3(x + 8)(x - 2)
Step-by-step explanation:
The intercept form of a quadratic function is y = a(x - r)(x - s), where r and s are the x-intercepts and a is the vertical stretch/compression factor.
If the intercepts are at (-8, 0) and (2, 0), and the vertical stretch is 3, just substitute these values into the intercept form formula, and you're done!
