7. If you get 2 imaginary answers when using the quadratic formula, how does this relate to
how many times (0, 1 or 2) a quadratic graph touches/crosses the x-axis?
Now finding f(0) to find f(0), subsitute x=0 into the function:
f(0)=3(0)^2-40(0)+180
8. Your teacher recently found an old Nintendo in a thrift store. Use the formula to predict
the value of the Nintendo in 2020? (Remember, x is the years after 1986, and y is the
value, in $.) Do you think this is a realistic prediction of the value of that Nintendo?
%
f(0)=0-0+180
f(0)=180
the value of f(0) is 180, which means that in the year 1986 when x=0 the nintendo video game
was worth $180.
The formula f(x)=3x2-40x+180 is in standard form of a quadratic formula. the standard form of a
quadratic formula is given as ax2+bx+c
in this forumla, a=3,b=-40, and c=180, which matches the standard form.
