Answer:

Step 1: a = 1, b = -4

Step 2: x = 2, f(2) = -9

Step 4: (5,0) and (-1,0)

Step 6: f(0) = -5

On the graph the points plotted are (-1,0) , (0,-5) , (2,-9) , and (5,0)

I am thinking of n consecutive positive integers, the smallest of which is m. What formula represents the largest of these integ
weqwewe [10]

Answer:

m+n-1

Step-by-step explanation:

I am thinking of n consecutive positive integers. The smallest of these numbers is m.

So,

  • a_1=m - the first number,
  • a_2=m+1 - the second number,
  • a_3=m+2 - the third number,
  • ...
  • a_n=m+(n-1)=m+n-1 - the nth number.

The list of n consecutive positive integers is

m, \ m+1,\ m+2,\ m+3, \ ... ,\ m+n-1

The largest integer is m+n-1

write a quadratic function in vertex form whose graph has the vertex (1,0) and passes through point (2,-17)
kobusy [5.1K]

Answer:

\displaystyle f(x) = -17(x-1)^2

Step-by-step explanation:

We want to write a quadratic function in vertex form whose vertex is (1, 0) and passes through the point (2, -17).

Recall that vertex form is given by:

\displaystyle f(x) = a(x-h)^2 + k

Where (<em>h</em>, <em>k</em>) is the vertex and <em>a</em> is the leading coefficient.

Since our vertex is at (1, 0), <em>h</em> = 1 and <em>k</em> = 0:

\displaystyle f(x) = a(x-1)^2

It passes through the point (2, -17). Hence, when <em>x</em> = 2, <em>y</em> = -17:

\displaystyle (-17) = a((2)-1)^2

Solve for <em>a: </em>

<em />\displaystyle a = -17<em />

<em />

In conclusion, our quadratic function in vertex form is:

\displaystyle f(x) = -17(x-1)^2
