The average rate of change of the function on the interval from [tex]x = 0[/tex] to [tex]x=2[/tex] is [tex]\boxed{ - 93.75}.[/tex]
Further explanation:
The formula for slope of line with points [tex]\left( {{x_1},{y_1}} \right)[/tex] and [tex]\left( {{x_2},{y_2}} \right)[/tex] can be expressed as,
[tex]\boxed{m = \frac{{{y_2} - {y_1}}}{{{x_2} - {x_1}}}}[/tex]
The formula for average rate of change can be expressed as follows,
[tex]\boxed{A\left( x \right) = \frac{{f\left( b \right) - f\left( a \right)}}{{b - a}}}[/tex]
Given:
The function is [tex]f\left( x \right) = 250{\left( {0.5} \right)^x}.[/tex]
Explanation:
The given function is [tex]f\left( x \right) = 250{\left( {0.5} \right)^x}[/tex].
Substitute [tex]0[/tex] for [tex]x[/tex] in function [tex]f\left( x \right) = 250{\left( {0.5} \right)^x}.[/tex]
[tex]\begin{aligned}f\left( 0 \right) &= 250{\left( {0.5}\right)^0}\\&= 250\times 1\\&= 250\\\end{aligned\\}[/tex]
Substitute [tex]2[/tex] for [tex]x[/tex] in function [tex]f\left( x \right) = 250{\left( {0.5} \right)^x}.[/tex]
[tex]\begin{aligned}f\left( 2 \right) &= 250{\left( {0.5} \right)^2}\\&= 250 \times 0.25\\&= 62.5\\\end{aligned}[/tex]
The average rate of change can be obtained as follows,
[tex]\begin{aligned}A\left( x \right)&=\frac{{f\left( 2 \right) - f\left( 0 \right)}}{{2 - 0}}\\&= \frac{{62.5 - 250}}{2}\\&= \frac{{ - 187.5}}{2}\\&= - 93.75\\\end{aligned}[/tex]
The average rate of change of the function on the interval from [tex]x = 0[/tex] to [tex]x=2[/tex] is [tex]\boxed{ - 93.75}.[/tex]
