Let
f(x)=
1
2

x
2
+4
.
the function
g(x)
is a vertical stretch of
f(x)
by a factor of 4.
what is the equation of
g(x)
?

enter your answer in the box.

g(x)
=

g(x) = 48x^2 + 4

Step-by-step explanation:

If f(x) = 12x^2 + 4 then g(x) would be the main x^2 term of the function times 4. This becomes g(x) = 48x^2 + 4. This will keep the vertex the same but stretch the function and make it skinnier in looks.

squares, rhombus, rectangles

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
