The answers x^1 or x^0<br> How??

pickupchik [31]

Remember a^(m) x a^(n) = a(m+n) & √a = a^(1/2)

===> x^(1/2 -3/2)+x(1/2 -1/2) ====> x^(-1)+x^(0) (any number Exp 0 =1)
X^(-1) +1 ===> 1/x +1 or (1+x)/x

How to Find the vertex of f(x)=-8x^2-8x+7

charle [14.2K]

Answer:

The answer to your question is: (1/2, 5)

Step-by-step explanation:

Parabola f(x) = 8x² - 8x + 7

y = 8x² - 8x + 7

Vertical Parabola equation

( x - h)² = 4p (y - k) Transform the original equation to this form

8x² - 8x = y - 7

8(x² - x + ( )²) = y - 7 Complete squares

8 (x² - x + (1/2)²) = y - 7 + 2 Simplification

8 (x² - x + 1/4) = y - 5

(x - 1/2)² = 1/8 (y - 5)

Finally Vertex

(1/2 , 5)
