This figure shows y=f(x), the graph of the function f. If the function g is defined as g(x)= 2•f(x)-1, what is the value of g(1)

uranmaximum [27]

This is a nice twist to see if you can read the graph and interpret what it means.

f(1) is the y value of the graph when x = 1

So start at x = 1 and find the y value. Go straight up. The point you reach is (1,3)

so g(1) = 2*f(1) - 1

g(1) = 2*3 - 1

g(1) = 5

Answer

g(1) = 5

Free_Kalibri [48]

$n\% \:\:off = (100 -n)\% \:\: of \:the\: original \:price$
$FinalPrice =$
$(Original Price \times(\frac{100\% - Discount}{100\%}))\times(\frac{100\% - Discount_2}{100\%}) =$
$\big(\$28.62\times(\frac{100\% - 25\%}{100\%})\big) \times(\frac{100\% - 15\%}{100\%}) =$
$\big(\$28.62\times(\frac{3}{4})\big) \times(\frac{17}{20}) \approx \$18.25$

Matt will pay $\$18.25$ for the mixer
