Question

F(x) varies directly with x². If f(x) = 12 when x = 2, write the equation for the variation and graph it showing at least three points. Draw a chart to show at least three ordered pairs that are on the graph.

Answer 1

HI!!!

Answer 2

\[f(x)=kx^2\\f(2)=k\times 2^2=12\\
4k=12\\
k=3\] so
\[f(x)=3x^2\)

Answer 3

oops
\[f(x)=3x^2\] plot that one
