\text{The point-slope form}\ y-y_1=m(x-x_1)\\\\\text{We have the point}\ \left(\dfrac{1}{2},\ -2\right)\ \text{and}\ m=3.\ \text{Substitute}\\\\y-(-2)=3\left(x-\dfrac{1}{2}\right)\qquad|\text{use distributive property}\\\\y+2=(3)(x)+(3)\left(-\dfrac{1}{2}\right)\\\\y+2=3x-\dfrac{3}{2}\\\\\text{The slope-intercept form:}\ y=mx+b\\\\y+2=3x-1\dfrac{1}{2}\qquad|\text{subtract 2 from both sides}\\\\\boxed{y=3x-3\dfrac{1}{2}}

Which function has only one x-intercept at (−6, 0)?
atroni [7]

Answer:

The only function that has only one zero at -6 is f(x) = (x + 6)(x + 6)

Step-by-step explanation:

We have a function:

f(x)=(x+6)(x+6)

This function is also equal to f(x)=(x+6)^2

This is the square of the binomial. It has only one zero

f(x)=(x+6)^2 = 0

If we take square root we get:

√(x+6)^2 = 0

x+6 =0

x= -6

The only function that has only one zero at -6 is f(x) = (x + 6)(x + 6)....
