Question

Find the domain and range of f(x)= 4x²+3x+1?

Answer 1

See below.

Explanation:

graph{4x^2+3x+1 [-5.55, 5.55, -2.775, 2.774]}

So before we start finding the domain and range, we need to graph it first before doing anything to find specific things of the graph.

So domain is how far left which for this graph is negative infinity to positive infinity

So range is how far right which is `7/16`
