Write an exponential function whose graph passes through the given points (0, - 2) and (- 1, - 4)

melamori03 [73]

Answer:

$y = 2(0.5) {}^{x}$

Step-by-step explanation:

Use the general formula of exponential equation

$y = ab {}^{x}$

Plug 0,2 into the function

$- 2 = ab {}^{0}$

$- 2 = a \times 1$

$a = - 2$

$y = - 2b {}^{x}$

$- 4 = - 2b {}^{ - 1}$

$2 = b {}^{ - 1}$

${2}^{ \frac{ 1}{ - 1} }$

$2 {}^{ - 1} = 0.5$

B=0.5

$y = 2(0.5) {}^{x}$

Suppose that w and t vary inversely and that t =1/5 when w = 4. Write a function that models the inverse variation, and find t w

Neko [114]

The correct answer to this question is this one: "4/45"

inverse variation ---> wt = constant let wt=k <span>put w=4, t= 1/5 and find k
</span>
So the correct answer for k is 4/5

wt = 4* (1/5) = 4/5 = k\
so your function is
wt = 4/5 or t= 4/(5w)

now to get t, when w=9, just put w=9 in t=4/(5w)
So that makes 4/45
