Answer:
55
Step-by-step explanation:
Answer:
Range → {y| y ≥ -11}
Step-by-step explanation:
Range of a function is the set of of y-values.
Given function is,
f(x) = 2x² + 6x - 8
By converting this equation into vertex form,
f(x) = 
= 
= ![3[(x+1)^2-\frac{11}{3}]](https://tex.z-dn.net/?f=3%5B%28x%2B1%29%5E2-%5Cfrac%7B11%7D%7B3%7D%5D)
= 
Vertex of the parabola → (-1, -11)
Therefore, range of the function will be → y ≥ -11
Answer:
Step-by-step explanation:
5(X+2) = 5x +10 +10 5x=10-10=-20
-20/5= -4
by folding at right angles
Answer:
multiply both the x value and y value by -1
