The given graphs show functions which have been transformed from the quadratic parent, f(x) = x2. Determine which transformation
Artyom0805 [142]

Answer:

The tansformations of were applied to the quadratic parent function to result in each graph are g(x), h(x) and d(x) with translation

Further explanation

Transformations definition is it involved by taking a preimage and transforming it in some way to produce an image.

Mathematical transformations have four main types: translation, rotation, reflection and dilation

Rotation is done by rotating an object about a fixed point without changing its size or shape

Translation is done by moving an object in space without changing its size, shape or orientation

Dilation is done by expanding or contracting an object without changing its shape or orientation

Reflection is done by flipping an object across a line without changing its size or shape

The given graphs show functions which have been transformed from the quadratic parent, f(x) = x^2f(x)=x

2

Which transformations were applied to the quadratic parent function to result in each graph?

Quadratic parent: f(x)=x^2f(x)=x

2

The graph is a parabola with V=(0,0)V=(0,0) at the origin

If x=1x=1 then f(1)=1^2 = 1f(1)=1

2

=1

Vertical shift means shifting in y axis. Whereas horizontal shift means shifting in x axis. Shift down means go to lower value of axis, whereas shift left goes to higher value of axis

For g(x)g(x) : vertical shift down 3 and horizontal shift left 3

For h(x)h(x) : reflection across the x-axis and vertical strecht of 3

Need help!<br> A. y= -x+2<br> B. y=2x+2<br> C. y=2x-1<br> D. y=5x+2
Anastaziya [24]

Answer:

\large\boxed{y=5x+2}

Step-by-step explanation:

\text{Let:}\\\\k:y=m_1x+b_1\\\\l:y=m_2x+b_2\\\\\text{then}\\\\k\ ||\ l\iff m_1=m_2\\\\k \perp l\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\\\==================================

\text{We have the equation of a line:}\\\\y=-\dfrac{1}{5}x+4\to m_1=-\dfrac{1}{5}\\\\\text{Therefore}\\\\m_2=-\dfrac{1}{-\frac{1}{5}}=-\left(-\dfrac{5}{1}\right)=5\\\\\text{Initially, our equation has the form}\\\\y=5x+b

\text{The line should pass through point (-1, -3).}\\\text{We substitute the coordinates of the point into the equation:}\\\\-3=5(-1)+b\\-3=-5+b\qquad\text{add 5 to both sides}\\-3+5=-5+5+b\\2=b\to b=2\\\\\text{Finally:}\\\\y=5x+2

PLEASE QUICK!!!
Ne4ueva [31]

Answer:

c

Step-by-step explanation:

since the line is going downward, it automatically means negative

and the first to answers mention adding which is positive, so A and B should be eliminated

since the slope is 72 (i dont feel like explaining why it is but trust me it is) that means the answer is c
