Identify the change in the parent function that will produce the related function shown as a dashed line

slega [8]

Answer:

Translate 2 units upward

$g(x) = \sqrt{x} + 2$

Step-by-step explanation:

See attachment for the functions

$f(x) = \sqrt x$

Required

Determine the change in f(x) that gives the dashed line

From the attachment, there is only one transformation from f(x) to the dashed line.

The transformation is a translation of 2 units, upward.

Let the dashed line be g(x)

g(x) will be:

$g(x) = f(x) + 2$

Substitute $\sqrt x$ for f(x)

$g(x) = \sqrt{x} + 2$

Solve the equation by completing the square. Round to the nearest hundredth if necessary. X^2 + 5x-10=0

viktelen [127]

$(*)\\(a+b)^2=a^2+2ab+b^2$

$x^2+5x-10=0\ \ \ |+10\\\\x^2+2\cdot x\cdot2.5=10\ \ \ |+2.5^2\\\\\underbrace{x^2+2\cdot x\cdot2.5+2.5^2}_{(*)}=10+2.5^2\\\\(x+2.5)^2=16.25\to x+2.5=\pm\sqrt{16.25}\\\\x+2.5\approx-4.03\ \vee\ x+2.5=4.03\ \ \ |-2.5\\\\x\approx-6.53\ \vee\ x\approx1.53$

What does it mean for data to be continuous?

ehidna [41]

Answer:

For data to be continuous, it can take on any value.

Step-by-step explanation:

For example, a line on a coordinate graph never stops at a certain point, if it does, it would be discrete.
