Final answer:
The equation of the translated function, f(x)=x^2, with a translation of 90 units up is g(x)=x^2+90.
Step-by-step explanation:
The equation of the translated function, f(x)=x^2, with a translation of 90 units up is g(x)=x^2+90.
To translate the function 90 units up, we add 90 to the original function. This is because each y-value of the original function is increased by 90 units to get the corresponding y-value of the translated function.
For example, if the original function has a point (x, y), the corresponding point on the translated function will have the same x-coordinate but a y-coordinate increased by 90 units.
