The graph represents g(x) is:
" On a coordinate plane, a parabola opens up. It goes through (2, 10), has a vertex at (5, 1), and goes through (8, 10) " ⇒ 1st answer
Step-by-step explanation:
Let us revise the translation
- If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)
- If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)
- If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k
- If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k
∵ The graph of f(x) = x² is translated to form g(x) = (x - 5)² + 1
∵ x² is changed to (x - 5)² and f(x) is added by 1
∴ The graph of f(x) is translated 5 units right and 1 unit up
∵ The parabola it goes through (-2, 4), has a vertex at (0, 0),
and goes through (2, 4)
- The x-coordinate of each point is added by 5 and the y-coordinate
of each point is add by 1
∴ The image of the point (-2 , 4) = (-2 + 5 , 4 + 1) = (3 , 5)
∴ The image of its vertex (0 , 0) = (0 + 5 , 0 + 1) = (5 , 1)
∴ The image of the point (2 , 4) = (2 + 5 , 4 + 1) = (7 , 5)
∴ The graph represents g(x) has a vertex point at (5 , 1)
The first answer only has a vertex at (5 , 1) let us check that the
parabola goes through points (2 , 10) and (8 , 10) by substituting
their x-coordinates in g(x) if the answer equal the y-coordinates,
then the points lie on the parabola
∵ x = 2 and y = 10
∴ g(x) = (2 - 5)² + 1 = (-3)² + 1 = 9 + 1 = 10 ⇒ same value of y-coordinate
∴ Point (2 , 10) lies in the parabola
∵ x = 8 and y = 10
∴ g(x) = (8 - 5)² + 1 = (3)² + 1 = 9 + 1 = 10 ⇒ same value of y-coordinate
∴ Point (8 , 10) lies in the parabola
The graph represents g(x) is:
" On a coordinate plane, a parabola opens up. It goes through (2, 10), has a vertex at (5, 1), and goes through (8, 10) "
