What is the inverse of f(x)=x^4+7 for x&gt;0 where function g is the inverse of function f?<br> -
Ann [662]

Answer:

g(x) = \sqrt[4]{x-7},~ x\geq 7

Step by step explanation:

y= f(x) = x^4+7\\\\\text{Replace x with y and solve for y:}\\\\~~~~~~~x = y^4 +7\\\\\implies y^4 = x-7\\\\\implies y = \pm\sqrt[4]{x-7}\\\\ \implies f^{-1}(x) = \pm\sqrt[4]{x-7}

Examine the following table of points, which are all on a certain line.
Lapatulllka [165]

\bf \begin{array}{|cc|ll} \cline{1-2} x&y\\ \cline{1-2} {-2}~~\ast&{4}~~\ast\\ 0&2\\ 1&1\\ {3}~~\ast&{-1}~~\ast\\ \cline{1-2} \end{array}~\hspace{10em} (\stackrel{x_1}{-2}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{-1}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-1-4}{3-(-2)}\implies \cfrac{-5}{3+2}\implies \cfrac{-5}{5}\implies -1

A baseball is thrown in a parabolic arc. Help?
Katyanochek1 [597]

Answer:

The maximum height of the baseball is 9 feet

Step-by-step explanation:

we have

p(t)=\frac{1}{2}gt^2+v_0t+p_0

where

p(t) ----> baseball position above the ground in feet

t ----> the time in seconds

v_0 ----> is the initial velocity in ft/sec

p_0 ---> initial position above the ground

we have

g=-32\frac{ft}{sec^2} \\\\v_0=16\frac{ft}{sec}\\\\p_0=5\ ft

substitute the given values

p(t)=\frac{1}{2}(-32)t^2+16t+5

p(t)=-16t^2+16t+5

This is the equation of a vertical parabola open downward

The vertex represent a maximum

Convert the quadratic equation in vertex form

p(t)=-16t^2+16t+5

Factor -16 leading coefficient

p(t)=-16(t^2-t)+5

Complete the square

p(t)=-16(t^2-t+\frac{1}{4})+5+4

p(t)=-16(t^2-t+\frac{1}{4})+9

Rewrite as perfect squares

p(t)=-16(t-\frac{1}{2})^2+9

The vertex is the point (0.5,9)

The maximum height of the baseball above the ground is the y-coordinate of the vertex

therefore

The maximum height of the baseball is 9 feet
