f(x)=x^2+3 from x=1 to x=2

Question

How do I find the solution to this problem?

Answer 1

Hello, Myah

 

f(x)= x^2+3 is a parabola concave up (looks like an U) with a vertex at (0, 3).  I don't know what you are asking, but maybe you want to evaluate the equation when x=1 and X=2.

 

f(1)= (1)^2+3=5     Evaluating using 1 for x.  (1,5) will be the point on the graph

f(2)= (2)^2+3=7     Evaluating using 2 for x/  (2, 7) will be the point on the graph. 

 

I hope this helps.  Maybe???? :)
