Answer:

a = 16, b = 6, c = - 4, d = - 9

Step-by-step explanation:

Substitute the appropriate values of x into the equation and evaluate.

x = - 3 : y = 1 - 5(- 3) = 1 + 15 = 16 → a

x = - 1 : y = 1 - 5(- 1) = 1 + 5 = 6 → b

x = 1 : y = 1 - 5(1) = 1 - 5 = - 4 → c

x = 2 : y = 1 - 5(2) = 1 - 10 = - 9 → d

Answer:

a=16; b=6, c= -4, d= -9

Step-by-step explanation:

f(x)=1-5x\\f(-3)  = 1-5(-3)=1+15=16\\f(-1) = 6\\f(1)=-4\\f(2)=-9

If f(x)=2x-3/5 , which of the following is the inverse of f(x)?
grigory [225]

Answer:

(5x+3)/2

Step-by-step explanation:

f(x)=(2x-3)/5

f(x)=y

y=(2x-3)/5

interchanging role of x and y

x=(2y-3)/5

5x=2y-3

5x+3=2y

y=(5x+3)/2

the inverse if f(x) = (5x+3)/2

F(x) = x2 - 4.<br> Find the inverse of the function
Lisa [10]

Answer:

f^{-1}(x) = √ x + 4

Step-by-step explanation:

step 1) replace f(x) with y

y = x² - 4

step 2) switch the x and y (because every (x, y) has a (y, x))

x = y² - 4

step 3) add 4 to both sides of the equal sign

x + 4 = y²

step 4) take the square root of both sides of the equal sign (the square root symbol cancels out the ²)

√ x + 4 = y

step 5) you know have the inverse of f(x) = x² - 4

f^{-1}(x) = √ x + 4

If y varies inversely as x2 and y = 100 when
love history [14]
Ans: (c)

y = k/x^2

when y = 100, x = 1
100 = k/1^2
k = 100

when x = 2,
y = 100/2
= 50
