Question

graph the function. identify a and compare

1. $f(x) = 5x^2$ $a = $ ______

Explanation:

Step1: Recall the standard form of a quadratic function

The standard form of a quadratic function is \( f(x) = ax^2 + bx + c \), where \( a \), \( b \), and \( c \) are constants, and \( a
eq 0 \). In the given function \( f(x)=5x^2 \), we can compare it with the standard form. Here, \( b = 0 \) and \( c = 0 \), and the coefficient of \( x^2 \) is 5.

Step2: Identify the value of \( a \)

From the standard form and the given function \( f(x)=5x^2 \), we can see that the value of \( a \) (the coefficient of \( x^2 \)) is 5.

Answer:

5
