Answer:
Third graph in the photo
Step-by-step explanation:
x^2+3x-4 can be factored as (x+4)(x-1). When y=0, x must be -4 or 1 to satisfy the equations, and thus the roots of the graph are at x=-4 and x=1. When x=0, y=(4)(-1)=-4. The only graph that satisfies both of these requirements is the third/last one.
Answer:
E + F = 2c^2 + 5c + 4
Step-by-step explanation:
E=6c^2-2c-1
F=-4c^2+7c+5
E+F= 6c^2 -2c -1 + -4c^2 + 7c + 5
E + F = 6c^2 - 4c^2 - 2c + 7c - 1 + 5
E + F = 2c^2 + 5c + 4
A function is a relationship between two sets of variables, the domain and the range, in which each value of the independent variable (the domain) is associated with exactly one value of the dependent variable (the range). Therefore, a graph is not of a function when there are two different values of y for a single value of x.
Answer: -4 -5 and 3 because there all greater than -4
