If f(x)=1-x^2+x^3, then f(-1)=

Answer 1

Answer:

Answer:

Well, we know that there exists a function f(x) such that f(x-1) is a direct transformation of its parent function. First we want to set x=x-1. Conceptually, it might be easier just to annotate one of the x’s as a completely different variable, because we know that x doesn’t equal x-1. So let’s rewrite as x=y-1 and solve for y.

We now have y=x+1 where y(x) is actually our parent function and y(x)=f(x+1). So take our equation f(x-1) and substitute each x with (x+1). So f(x)=2(x+1) + 3

f(x)= 2x + 5. We can check this by finding f(x-1) because it should equal 2x+3.

f(x-1)= 2(x-1) + 5

f(x-1)= 2x + 3.

Find the perimeter of WXYZ. Round to the nearest tenth if necessary.

Answers

Answer:

C. 15.6

Step-by-step explanation:

Perimeter of WXYZ = WX + XY + YZ + ZW

Use the distance formula, $d = √((x_2 - x_1)^2 + (y_2 - y_1)^2)$ to calculate the length of each segment.

✔️Distance between W(-1, 1) and X(1, 2):

Let,

$W(-1, 1) = (x_1, y_1)$

$X(1, 2) = (x_2, y_2)$

Plug in the values

$WX = √((1 - (-1))^2 + (2 - 1)^2)$

$WX = √((2)^2 + (1)^2)$

$WX = √(4 + 1)$

$WX = √(5)$

$WX = 2.24$

✔️Distance between X(1, 2) and Y(2, -4)

Let,

$X(1, 2) = (x_1, y_1)$

$Y(2, -4) = (x_2, y_2)$

Plug in the values

$XY = √((2 - 1)^2 + (-4 - 2)^2)$

$XY = √((1)^2 + (-6)^2)$

$XY = √(1 + 36)$

$XY = √(37)$

$XY = 6.08$

✔️Distance between Y(2, -4) and Z(-2, -1)

Let,

$Y(2, -4) = (x_1, y_1)$

$Z(-2, -1) = (x_2, y_2)$

Plug in the values

$YZ = √((-2 - 2)^2 + (-1 -(-4))^2)$

$YZ = √((-4)^2 + (3)^2)$

$YZ = √(16 + 9)$

$YZ = √(25)$

$YZ = 5$

✔️Distance between Z(-2, -1) and W(-1, 1)

Let,

$Z(-2, -1) = (x_1, y_1)$

$W(-1, 1) = (x_2, y_2)$

Plug in the values

$ZW = √((-1 -(-2))^2 + (1 - (-1))^2)$

$ZW = √((1)^2 + (2)^2)$

$ZW = √(1 + 4)$

$ZW = √(5)$

$ZW = 2.24$
