If you're asking if you can subtract this, for example:
x³ - x²
No. They must have the same exponent to be compatible. For example:
4x² - x² = 3x²
3.25 - 3 = 0.25
3 - 2.75 = 0.25
2.75 - 2.5 = 0.25
2.5 - 2.25 = 0.25
Since we subtracted those numbers, it means we are decreasing.
Therefore, the answer is decrease by 0.25.
By understanding and applying the concepts of dilation and <em>quadratic</em> functions, the function g(x) is a <em>vertically dilated</em> version of f(x) by a factor of 5.
<h3>How to compare the graphs of two functions</h3>
In this questions we know two <em>quadratic</em> equations of the form y = a · x². f(x) is known as the <em>canonical</em> function as a = 1 and g(x) is the consequence of <em>dilating</em> f(x) <em>vertically</em> by a factor of 5. Now we proceed to present graphically between the two functions.
In a nutshell, the function g(x) is a <em>vertically dilated</em> version of f(x) by a factor of 5.

For this problem you can do it a couple of ways. the way that i chose to do it was by moving everything to get y alone, but you can also find the x and y intercepts by plugging in 0 for the other variable (what i mean by this: x+5y=10; plug in 0 for x and your y intercept is 2). then you graph each equation and the solution to the system (if you also need that) would be (-4,3) since this is where the lines intersect.
