Y = 4x+1 y=x^2 + 2x - 2 A.6,2 B. 2,6 C. -6,2 D. -6,-2

natta225 [31]

Answer:

The solution is (3,13) and (-1,-3). So none of the mentioned options is correct.

Step-by-step explanation:

Given that

$y = 4x + 1 (i)$

$y = x^2 + 2x -2 (ii)$

Now, by susbstituting the value of 'y' from equation i to equation ii, we get

$4x+1=x^2 + 2x -2$

$0=x^2 + 2x -2-4x-1$

$0=x^2 + (2x -4x) +(-2-1)$

$0=x^2 + (-2x) +(-3)$

$0=x^2 -2x -3$

$x^2 -2x -3 = 0 (iii)$

Now by factorization, equation iii can be written as

$x^2 -3x +x -3 = 0$

$x(x -3) + 1(x -3) = 0$

$(x -3)(x +1) = 0$

x = 3 and x = -1

By putting the values of x in equation i, we get

y = 4(3) + 1

y = 12 +1

y = 13

and

y = 4(-1) + 1

y = -4 +1

y = -3

Therefore, the solution is (3,13) and (-1,-3). So none of the mentioned options is correct.

Find the inverse of f(x) = x2 - 5:

Volgvan

Answer:

g(f(x))=x g ( f ( x ) ) = x , f−1(x)=√x+5,−√x+5 f - 1 ( x ) = x + 5 , - x + 5 is the inverse of f(x)=x2−5 f ( x ) = x 2 - 5 .

Step-by-step explanation:

( f ( x ) ) = x , f−1(x)=√x+5,−√x+5 f - 1 ( x ) = x + 5 , - x + 5 is the inverse of f(x)=x2−5 f ( x ) = x 2 - 5 .
