Question

Janie is analyzing a quadratic function f(x) and a linear function g(x). Will they intersect?

f(x) g(x)
graph of the function f of x equals two times x squared, plus 1
x g(x)
1 2
2 4
3 6

Answer 1

@phi

Answer 2

\(\large\color{black}{ \displaystyle \color{blue}{ f(x)=2x^2+1} }\)
is that correct ?

Answer 3

to answer I would first find the equation of the line for g(x)
you have two points (1,2) and (2,4)
you can find the slope and the y-intercept, and get the equation
can you do that ?
