Answer:

Hence the function which has the smallest minimum is: h(x)

Step-by-step explanation:

We are given function f(x) as:

  • f(x) = −4 sin(x − 0.5) + 11

We know that the minimum value attained by the sine function is -1 and the maximum value attained by sine function is 1.

so the function f(x) receives the minimum value when sine function attains the maximum value since the term of sine function is subtracted.

Hence, the minimum value of f(x) is: 11-4=7 ( when sine function is equal to 1)

  • Also we are given a table of values for function h(x) as:

x    y

−2   14

−1   9

 0   6

  1   5

 2   6

 3   9

 4   14

Hence, the minimum value attained by h(x) is 5. ( when x=1)

  • Also we are given function g(x) ; a quadratic function passing through (2,7),(3,6) and (4,7)

so, the equation will be:

g(x)=ax^2+bx+cHence on putting these coordinates we will get:

a=1,b=3 and c=7.

Hence the function g(x) is given as:

g(x)=x^2-6x+15

So,the minimum value attained by g(x) could be seen from the graph is at the point (3,6).

Hence, the minimum value attained by g(x) is 6.

Hence the function which has the smallest minimum is h(x)

write a quadratic function that has a graph that contains the following points, (-2, 0), (4, -12), (5,0).
ankoles [38]

Answer:

f(x) =  2x^2 - 6x - 20.

Step-by-step explanation:

(-2, 0) and (5, 0)  are 2 zeroes of the function so we can write the function as

f(x) =  a(x + 2)(x - 5)   where a is a constant.

Now as (4, -12) is a point on the graph:

-12 = a(4 + 2)(4 - 5)

-12 = a * 6 * -1

-6a = -12

a = 2.

So f(x) = 2(x + 2)(x - 5)

f(x) =  2x^2 - 6x - 20.

What is the value of x to the nearest tenth?
Alex_Xolod [135]
Hi there!

In order to solve for x, we'll need to use a trigonometry ratio. In this case, we'll use tangent, which is opposite over adjacent.

Here is our equation:
tan(37)/1 = x/2.1

Cross-Multiply:
x = tan(37) * 2.1

Solve:
x = 1.8 (rounded to the nearest tenth)

Hope this helps!! :)
