Yes, thank you! (Thanks also to Carl Woll and Gianluca Gorni, who
privately sent the same solution.)
But this solution, using
TraditionalForm[HoldForm[y = f[x]]]
within the Text function, is not foolproof (as Gianluca Gorni pointed
out to me): Mathematica will still insist on changing the form in some
instances, e.g.,
TraditionalForm[HoldForm[y = f[x] + c]]
displays (with the letters italicized Times) as:
y = c + f(x)
