Answer:
f(x)=x^2
g(x)= -4(x^2)+2
(0,2)
Step-by-step explanation:
Answer:
6√2
Step-by-step explanation:
√32+√18-1√4
√16×2+√9×2-1√2
4√2+3√2-1√2
6√2
Rearrange to: x^2 + 18x - 25 = 0
Then factorise (I like to do it by completing the square):
(x + 9)^2 -81 -25 = 0
(x + 9)^2 = 106
x + 9 = sqrt(106)
The sol'ns are:
x = -9 + and - sqrt(106)
Answer:
(x, y, z) =(1, -1,2)
Step-by-step explanation:
.............
In this question , we have to find, which option represents inverse functions.
Let's check out option b
Let it be y
So we have

Switching x and y and solving for y,

Performing cross multiplication

Combining like terms


Which is same as of the other function.
So correct option is b .
