The scale factor that doubles the sizes of a figure

When we apply a scale factor "c" to a parent function f(x), the resulting function is 
g(x)=c*f(x).

A scale factor is the ratio of the transformed function and the original function, or
scale factor = (transformed function)/(original function).

If the size is doubled, the scale factor is 2.

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
