Find the critical point of the function f(x) = x2 – 2x + 7.
vesna_86 [32]

Answer:

x=1 is a critical point of the function f(x).

Step-by-step explanation:

f(x)=x^2-2x+7

Differentiate both sides w.r.t. x

\Rightarrow f'(x)=2x-2

Now, f'(x)=0

\therefore 2x-2=0

\Rightarrow 2x=2

\Rightarrow x=1

Hence, x=1 is a critical point of the given function.

Is this equation an infinite solution, no solution, or one solution?? 36-7x=-7(x-5) is
Rzqust [24]

Answer:

no solution

Step-by-step explanation:

36-7x=-7(x-5)

first what we have to do is do the multiplications

36 - 7x = -7x + 35

we add 7x from both sides

36 - 7x + 7x = - 7x + 7x + 35

36 = 35

we subtract 36 from both sides

36 - 36 = 35 - 36

0 = -1

This means that the system has no solution

if we look at the equation at the beginning we can realize since we have the same term on both sides "-7x" and a term without x on each side, this means that we can never find a value of x that meets the conditions
