The parent function is y = x^2
There is a compression of 3:
y = 3x^2
There is a shift by 1 unit to the left:
y = 3(x + 1)^2
2x2x5 is the prime factorization
Substitute x=9 and y=-2 into equation,
Left hand side=-2
Right hand side=1/3(9)+4= 3+4=7
Because LHS doesn’t = with RHS, the point (9,-2) doesn’t satisfy with the equation
Therefore the point doesn’t go through y=1/3x +4.
The answer is certainly c because i did that and got it right
#3.
in this case, all you need to do is to look at the intersecting point. each units represent 2, the coordinates of the intersection are (4,-1), so D is the choice.
#4. B is the choice. two lines either intersect once (one solution), never (parallel, no solution), or overwrap (merge, infinite solutions)
