Compare the functions below: Which function has the smallest minimum?

anzhelika [568]

Answer:

D. All three functions have the same minimum value

Step-by-step explanation:

f(x) = -3 sin (x-pi) +2

Sin has a minimum value of -1, but since it is multiplied by a negative, we want its maximum value

sin has a maximum of 1

f (min) = -3(1) +2 = -1

g(x) has a minimum at x =3

g(minimum) = -1

h(x) = (x+7)^2 -1

The smallest a squared value can be is zero

= 0 -1

h(min) =-1

(x+0.5)^2=0.64 solve the equation for x

MrRa [10]

Hi,

$\sqrt{(x+\frac{1}{2}) ^{2} } = \sqrt{\frac{64}{100}} \\\\$

= (x + 1/2) = 8/10

= ( $\frac{2x+1}{2}$ ) = 8/10

= 20x + 10 = 16

= 20x = 6

= x = 6/20

= x = 3/10

x => 0,3
