Which function grows at the fastest rate for increasing values of x? h(x)=2x f(x)=4x2+9x g(x)=18x

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.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
