Answer:
28
Step-by-step explanation:
We begin with the expression [tex]2x^2-y^1+3x^0[/tex]
First, we can simplify this expression before we plug in our values
[tex]2x^2-y^1+3x^0\\\\2x^2-y+3[/tex]
Now that it is in its simplest form, we can now evaluate the expression by plugging in x=4 and y=7
[tex]2x^2-y+3\\\\2(4)^2-7+3\\\\2(16)-4\\\\32-4\\\\28[/tex]
