Factor x2 − 4x + 5. Prime (x + 5)(x − 1) (x − 5)(x − 1) (x + 5)(x + 1)

1 answer:

8 0

1) Prime
<span>2) (x + 5)(x − 1) = x²-1x+5x-5= x²+4x-5
3) (x − 5)(x − 1)= x² -1x -5x +5= x² -6x +5
4) (x + 5)(x + 1) = x² +1x +5x+ 5x = x² +6x+5

It is 1) Prime

Determine the quadratic function f whose graph is given. The vertex is (1,-3) and y-intercept is -2

Nesterboy [21]

Answer:

Vertex form: $f(x)=(x-1)^2-3$

Standard form: $f(x)=x^2-2x-2$

Step-by-step explanation:

A quadratic function in vertex form is $f(x)=a(x-h)^2+k$ where $(h,k)$ is the vertex.

We are given $h=1,k=-3$ .

Let's plug that in:

$f(x)=a(x-1)^2-3$ .

Now let's find $a$ .

We will use the $y$ -intercept $(0,-2)$ to find $a$ .

$f(0)=a(0-1)^2-3$

$-2=a(0-1)^2-3$

$-2=a(-1)^2-3$

$-2=a(1)-3$

$-2=a-3$

$1=a$

So the function in vertex form is:

$f(x)=(x-1)^2-3$ .

In standard form, we will have to multiply and combine any like terms.

Let's do that:

$f(x)=(x-1)(x-1)-3$

$f(x)=x^2-x-x+1-3$

$f(x)=x^2-2x-2$
