Alex says that the function f(x) = (3x)2 represents a vertical stretch of the quadratic parent function by a factor of 3. Marta

gavmur [86]

Our parent function is f(x)=x^2. A vertical stretch by a factor of k means that every point (x,f(x)), has been transformed into (x,kf(x)). Alex is clearly incorrect as our parent function has been transformed to (x,9f(x)), not (x,3f(x)). A horizontal stretch(or compression) by a factor of k means our function has been transformed to (x/k,f(x)). Here, Marta is saying our function should look like (3x,f(x)). This can also be achieved by plugging 3x into the parent function, which would give us f(3x)=(3x)^2, so it seems that Marta is the correct one.

What is the answer to 11x+4+51+2x+8=180

Digiron [165]

Hi,

Work:

Equation;

$11x + 4 + 51 + 2x + 8 = 180$

Collect like terms and calculate sum of positive numbers.

$13x + 63 = 180$

Move constant +63 to the right side and change its sign.

$13x = 180 - 63$

Subtract numbers.

$13x = 117$

Divide both sides of equation with 13.

$x = 9$

Hope this helps.
