Find the slope, then use substitute the slope and one of the given points into slope-intercept form.

Slope is change in y over change in x. (7-3)/(-3-1)=-1

Slope-inttercept form is y = mx+b.
3 = -1(1)+b
b=4

y = -x + 4

$13, 666.67
because you would do 820 divided by 0.06 and you get 13,666.6667 which you round to 13,666.67

The function f(x) is a quadratic function and a limited table of values is provided below. Write the equation of the quadratic p

OverLord2011 [107]

Answer:

f(x) = 3x^2 -21x +36

Step-by-step explanation:

The table gives the x- and y-intercepts, which are sufficient to write the equation in factored form. The x-intercepts of 3 and 4 tell you that factors are (x -3)(x -4). When x=0, this product is (-3)(-4) = 12, but the y-intercept value is 3 times that: 36. So, the factored equation is ...

f(x) = 3(x -3)(x -4)

Multiplying this out, we get ...

f(x) = 3(x^2 -7x +12)

f(x) = 3x^2 -21x +36
