How does f(x) = 3* change over the interval x = 4 to x = 57
Vilka [71]

f(x) increase by a factor of 3

Explanation:

        Given that f(x)= 3* and the interval is x=4 to x=57

        Now we put the value for x is 4 to 57 then value of f(x) increase with the multiply of 3.

        Because the x is multiplied with 3 i.e., 3*

        So f(x) increase by a factor of 3.

        If we put x=4, then f(x)= 12     (∵ 3×4=12)

        If we put x=5, the f(x)= 15       (∵ 3×5=15)

        If we put x=6,the f(x)= 18             (∵ 3×6=18)

similarly., values of x= 7,8,9,...155.

        Then,

        If we put x=56, the f(x)=168

        This process will continue until f(x)=171 for x=57.

Find the value of C that completes the square for x^2-2x + C
solniwko [45]

Answer:

C = 1.

Step-by-step explanation:

x^2 - 2x = (x - 1)^2 - 1   so:

x^2 - 2x + C = (x - 1)^2 - 1 + C

So to get a perfect square  C must be 1 ( as -1 + 1 = 0):-

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

Checking  this:

x^2 - 2x + 1

= (x - 1)(x - 1) which is a perfect square./
