Find a quadratic model for the set of values: (-2, -20), (0, -4), (4, -20). Show your work.

Ivahew [28]

Ok... so this question can be solved by using simultaneous equations.

Use the general from of a parabola

$y = ax^2 + bx + c$

you know the value of c, the y-intercept... y = -4

which means the equation is

$y = ax^2 + bx - 4$

now use the other 2 points to get 2 equations in 2 unknowns

(-2, -20) just substitute

$-20 = (-2)^2a + (-2)b - 4 ~~~or~~~ -20 = 4a - 2b - 4$

this becomes

$4a - 2b = -16$

now the other equation using (4, -20)

The simplified form is

Find the range of ƒ(x) = 3g – 5 for the domain {–1.5, 2, 4}

timofeeve [1]

-1.5 ------ f(x) = 3(-1.5) - 5
= -4.5 -5
= 9.5

2 -------- f(x) = 3(2) - 5
= 6 -5
= 1

4 -------- f(x) = 3(4) - 5
= 12 - 5
= 7
(9.5, 1 , 7)
