B increase because it says that he went 4 points more
Answer:
the new equation is f(x)=x^2-4
vertex- (0,-4)
zeros- (-2,2)
y-intercept- (-4)
and it has a minimum
Step-by-step explanation:
Answer:
<u>scalene</u>
Step-by-step explanation:
Length of XZ = √3² + 4² = √25 = 5
Length of ZY = √1² + 7² = √50 = 5√2
Length of XY = √4² + 5² = √41
As all lengths are different, the triangle is <u>scalene</u>
Answer: y = 10x + 30 is the correct answer
