Front

Is this a function?

Back

False

Front

If f(x)= ax+b, where a and b are integers, f(-1)=-5 and f(3)=3, then a and b are equal to

Back

a=2, b=-3

Front

If (x-2,y+5)=(-2,1/3) are two equal ordered pairs, then value of x and y.

Back

x=0, y=-14/3

Front

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

Back

Domain: {0, 1, 2, -4} Range: {1, -3, -4}

Front

Is the relation a function?

Back

No, because the x-value 11 has two y-values pair with it.

Front

Which relation is NOT a function? Options: {(1,-5), (3,1), (-5,4), (4,-2)}, {(2,7), (3,7), (4,7), (5,8)}, {(1,-5), (-1,6), (1,5), (6,-3)}, {(3,-2), (5,-6), (7,7), (8,8)}

Back

{(1,-5), (-1,6), (1,5), (6,-3)}
