Ew. Composition of functions. Ok, f(g(x)) is what that fancy notation means. So, you would take g(x) & substitute that into wherever x is in f(x). So we get something crazy like f(x)= 4 - (.5x - 2)^2 Now, we foil out the squared quantity: f(x)= 4 - (.25x^2 - x - x + 4) Can you believe they call that simplification? f(x)= 4 - .25x^2 + 2x -4 Almost there... f(x)= -.25x^2 + 2x Hope this helps!

Do the points lie on the line of the given equation. Y = -0.25 X. Show your work.

meriva

Yes all the points lay in the line.
Insert the x coordinate into x giving you your y

Michela says that the modes of the two data are the same so the median and mean must also be the same. what is michela’s error?

aev [14]

Answer: median and mean are the same

Step-by-step explanation:

The error committed by Michela is by saying

The median and mean are the same.

Because in statistics, we can't use mode to predict the median and the mean.

Point slope graph y+2÷4(x+5)

ladessa [460]

Answer:

See attachment for graph

Or

The slope intercept form is $y=4x+18$

Step-by-step explanation:

Assuming you want to graph the straight line given in point-slope form as

$y+2=4(x+5)$

Then we need at least two points on this line

When we compare to the point-slope formula $y-y_1=m(x-x_1)$ then we obtain (-5,-2) as a point on this line so we plot it.

When x=0, y=4(0+5)-2=18 so we plot (0,18)

We then draw a straight line through as shown in the attachment.

On the other hand, if you had wanted the equation slope intercept form, then we expand to obtain:

$y+2=4x+20$

$\implies y=4x+20-2$

$\implies y=4x+18$
