What's the rate of change of y=4x+7?

2 answers:

8 0

Since this is a linear equation the rate of change or velocity is constant. Take the derivative of y with respect to x...

dy/dx=4

This is commonly called the slope of the line. All lines because they are straight have a constant velocity.

The slope/growth is 4.
Y= 4x+7
Figure 0 / y intercept= 7
The slope / growth = 4

Answer:

The graph has only one x-intercept

Step-by-step explanation:

we have

$f(x)=-4x^2+12x-9$

we know that

The discriminant of a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$D=b^{2}-4ac$

in this problem we have

$f(x)=-4x^2+12x-9$

$a=-4\\b=12\\c=-9$

substitute

$D=12^{2}-4(-4)(-9)$

$D=144-144$

$D=0$

The discriminant is zero

That means ----> The quadratic equation has one real solution

The graph has only one x-intercept
