Write the equation of the linear function for which f(0)=3 and f^-1(0)=-2

Semmy [17]

We know that if f(a)=b then $f^{-1}(b)=a$
and
if $f^{-1}(a)=b$ then f(b)=a
so

since $f^{-1}(0)=-2$ therefor, f(-2)=0

we have 2 points, (-2,0) and (0,3)

we can use slope intercept form
y=mx+b
m=slope
b=y intercept

we have when x=0, y=3, that is the y intercept
y=mx+3

substitute the other point
(-2,0)
x=-2, y=0
0=-2m+3
-3=-2m
divide both sides by -2
$\frac{3}{2}=m$

the equation is
$y=\frac{3}{2}x+3$
or
3x-2y=-6 in standard form

The graph of y = 4x2 - 4x – 1 is shown.

11Alexandr11 [23.1K]

Answer:

i) The approximate solutions are: $x_{1} \approx -0.207$ , $x_{2} \approx 1.207$ .

ii) The approximate solutions are: $x_{1}\approx -0.5$ , $x_{2} \approx 1.5$ .

Step-by-step explanation:

i) The best approach to estimate graphically the solution of $4\cdot x^{2} - 4\cdot x - 1 = 0$ is graphing the following system of equations:

$y = 4\cdot x^{2}-4\cdot x - 1$ (1)

$y = 0$ (2)

And labeling the points in which both intersects each other. We include the result in the image 'solution-i'. The approximate solutions are: $x_{1} \approx -0.207$ , $x_{2} \approx 1.207$ .

ii) The best approach to estimate graphically the solution of $4\cdot x^{2} - 4\cdot x - 1 = 2$ is graphing the following system of equations:

$y = 4\cdot x^{2}-4\cdot x - 1$ (1)

$y = 2$ (2)

And labeling the points in which both intersects each other. We include the result in the image 'solution-ii'. The approximate solutions are: $x_{1}\approx -0.5$ , $x_{2} \approx 1.5$ .
