Shrink the graph of f(x)=x+5 horizontally by a factor of 1/2

Let be a horizontally scaled version of by

Step-by-step explanation:

Given:

Scaling a function by a scalar horizontally, is just multiplying and or . In your case, we have to note that shrinking is just another specific word for scaling. If we scale by scalar, horizontally (), would flatten or spread out which would be the opposite of shrinking. To truly shrink , we must have a scalar greater than . So the scalar must be the opposite and it is .

We let be the result when we shrink horizontally by a scalar, .
