Given y = 4x² - 3 which statement is true?
1) the equation is written in vertex form.
the axis of symmetry is x = 0 and the vertex is (-3, 0)
2) the equation in not written in vertex form.
you cannot determine the axis of symmetry and vertex from this statement.
3) the equation is written in vertex form.
the axis of symmetry is x = 0 and the vertex is(0, -3)
4) the equation is written in vertex form.
the axis of symmetry is y = -6 and the vertex is (4, -3)

Tomas is making trail mix using granola and walnuts. he can spend a total of $12 on the ingredients. he buys 3 pounds of granola that costs $2.00 per pound. the walnuts cost $6 per pound. he uses the equation to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. he solves the equation for y, the number of pounds of walnuts he can buy. answer- b tomas added 6 to both sides of the equation instead of subtracting 6. just took the test

How do i do this activity, is appreciated
