Answer:
Option 2. f(x) = 4x² + 9x
Step-by-step explanation:
In this question we have to tell which function grows at the fastest rate for increasing values of x.
1) h(x) = 2x It's a linear function increasing with the value of x.
2). f(x) = 4x²+9x It's a function representing parabola. Moreover the value of the function increases exponentially as the function is in the form of quadratic equation.
3). g(x) = 18x it's again a linear function.
Therefore out of three functions Function 2 will grow at the fastest rate for increasing values of x.
