How many solutions does the system have? <br> y=−2x+1 <br> y=−2x^2+1

balu736 [363]

Answer:

The system has two distinct solutions.

Step-by-step explanation:

The given system of equations are:

$y=-2x+1--(1)$

and

$y=-2x^2+1---(2)$

In order to determine the number of solutions the two equations have, we need to equate the two equations to obtain,

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

We now group all terms on the left hand side and equate everything to zero.

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

$x^2-x=0$

This is now a quadratic equation in $x^2$ with $a=1,b=-1,c=0$ .

At this stage we check the number of solutions using the discriminant.

$D=b^2-4ac$

$\Rightarrow D=(-1)^2-4(1)(0)=1$

Since the discriminant is greater than zero, the equation will have two distinct roots.

Therefore the system of equations has exactly two distinct solutions.

If you wish to see these solutions, you can continue as follows;

We factor $x$ to obtain,

$x(x-1)=0$

$\Rightarrow x=0,x-1=0$

$\Rightarrow x=0,x=1$

When $x=0,y=-2(0)+1$

Then we have,

$x=0,y=1$

When $x=1,y=-2(1)+1$

Then we have,

$x=0,y=-1$

Analyze a graph In Exercise,analyze and sketch the graph of the function.Label any relative extrema, points of inflation,and asy

ZanzabumX [31]

Answer:

Step-by-step explanation:

Given is a function f(x)

$f(x) = e^x -e^{-\frac{{x}}{2}$

We have to analyse and sketch the graph

X intercept : Put y =0, we get x=0

Y intercept: Put x =0 , we get y =0

No exception for x or y and hence set of all real numbers is domain and range.

$f'(x) = (e^x +1/2 e^{-\frac{{x}}{2})$

f' becomes 0 not at finite points

So relative extreme
