The location of the vertex tells you the horizontal and vertical shift. (The parent function f(x) = x² has its vertex at the origin, (0, 0). The vertical distance of the point 1 unit left or right of the vertex in relation to the vertex tells you the vertical scale factor (stretch).
g(x) = f(x +3) -3
horizontal shift left 3
vertical shift down 3
h(x) = -3f(x)
reflection across the x-axis
vertical stretch of 3
d(x) = f(x -3) -3
horizontal shift right 3
vertical shift down 3
3 3/4 pounds so 3×3/4 = 2 1/4(mixed fraction)
2 1/4÷ 1/8= 2 1/4 × 8/1
for fraction division, yo
u keep the first fraction and flip the second fraction around. than you change the divide sign to multiply sign to find the answer
combine your like terms and get x by its self
9. L’(-1,-3) Z’(-5,-5) F’(-4,-2)
10. B
I think these are right if they aren’t I’m sorry
To solve a function like this, simply put the numerical value in place of the unknown variable for which you have to find the solution, for instance '-3' in this case.
g(x) = 2x-2
so to find g(-3), we just need to replace the x in the given expression by '-3'. Working is shown below:
g(x) = 2x-2
putting '-3' in place of x
g(-3) = 2(-3) - 2
g(-3) = -6 -2
g(-3) = -8
