Answer:Function 1 has the least minimum value and its coordinates are (-1, -3).

Step-by-step explanation:

Any quadratic function can be written in the form:

f(x)=ax^{2} +bx+c

The x of the vertex can be fiund by x=-b÷2a

Function 1 is given by:f(x)=4x^{2} +8x+1

Comparing the quadratic equations we have a=4,b=8,c=1.

The x of the vertex is -b÷2a=-8÷2(4)=- 8÷8= -1.

The y of the vertex can be found by substituting x= -1 in the original function and solving for y.

y=4(-1^{2} )+8(-1)+1=-3

Vertex of f(x)=(-1,-3)

For function g(x) minimum is at (0,0)

Hence Function 1 has the least minimum value and its coordinates are (-1, -3).

Funtion ! in vertex form is given by
<span>f(x) = 4x^2 + 8x + 1</span> = 4(x^2 + 2x + 1/4) = 4(x^2 + 2x + 1 + 1/4 - 1) = 4(x + 1)^2 + 4(-3/4) = 4(x + 1)^2 - 3
Thus, the least minimun value is (-1, -3)
Also, the least minimum value of function 2 is (-1, 0)

Therefore, function 1 has the least minimum value at (-1, -3)

If you were to invest only $1, how much simple interest would you have if the rate was 4.6%? Use the following years for each sc
tiny-mole [99]

Answer:

30 years: 1.38

45 years: 2.07

65 years:2.99

Step-by-step explanation:

$1x0.046=0.046

0.046x30=1.38

0.046x45=2.07

0.046x65=2.99

this is assuming that it gets interest yearly and that they don't want the original amount included.
