Question
y=3x"2" and y=2.5x"2"
x^2 simply means x multiplied by x.
On your calc., just press [x] [*] [x].
Of course, x represents a variable, so you need to change that each time. You can consider a range of input values for x.
For example,
x={-5,-4,-3,-2,-1,0,1,2,3,4,5}.
Now,
x*x={25,16,9,4,1,0,1,4,9,16,25}.
Finally,
y=3*x*x={75,48,27,12,1,0,...etc}.
Same approach for the second one.

Expertise
When I work through problems, I like to emphasize concepts which I believe are worth noting. I will try to answer questions in the following areas, but not at the advanced level. Algebra. Sequences & Series. Trigonometry. Functions & Graphs. Coordinate Geometry. Quadratic Polynomials. Exponential & Logarithms. Basic Calculus. Probability, Permutation and Combination. Mathematical Induction. Complex numbers. Physics problems.
Experience
I have worked as a teaching assistant in college. My hope is that more people will share knowledge without boundary, give help without seeking recognition or monetary rewards.
