The phrase "a function of both energy" is correct and usable in written English.
It can be used in contexts discussing relationships or dependencies between variables, particularly in scientific or mathematical discussions.
Example: "The efficiency of the system is a function of both energy input and output."
Alternatives: "dependent on both energy" or "related to both energy".
The pulse profile was highly variable as a function of both energy and time.
By referring the observation sequence indicated by Fig. 2a, b, we compute the expected count rate during one spin period as a function of both energy and pitch angle of electrons.
Steady-state ATP levels, which were not different between GA480 compared to WT, are a function of both energy production and consumption rates and do not by themselves allow conclusions regarding ATP flux.
Thus, we demonstrate that the wettability of the surface can be varied as a function of both the low surface energy additive and the annealing carried out whilst maintaining the overall surface topography.
The degree to which blending enables smaller battery energy capacities is evaluated as a function of both daily driving distance and energy (fuel and electricity) pricing.
Body fat gain and body fat loss are a function of energy balance, where energy balance is primarily a function of energy intake (Westerterp 2010).
Because 24-hour recall is an imperfect measure of caloric intake and has known biases by BMI [28], [29], [30], [31], we compared the consumption pattern of 2+ sodas per day as a function of both BMI category and quartile of energy intake.
A contribution of a hydrogen atom to the dosemeter sensitivity was numerically evaluated as a function of both depth in the radiator and neutron energy.
The degradation in image quality is primarily due to the separation between the detector plane and the effective focal plane, which is a strong function of both energy and off-axis angle (see Figure 4.11).
Second, the model is applied to study the contribution of drifts and the enhancement of polar perpendicular diffusion in the heliosheath to the total modulation in the heliosphere as a function of energy for both polarity cycles of the magnetic field during solar minimum conditions.
In addition, we have also simulated optical and mode gain as a function of photonic energy and lasing wavelength in both TE and TM modes.
