we have f (x)= -3x + 10
so f(-5)= (-3)(-5) +10 = 15 + 10 = 25
we have g (x) = x^2 - 7x
so g(2)= 2^2 - 7.2 = 4 - 14 = -10
we have f (x)= -3x + 10
so f(4m)= -3(4m)+10 = -12m + 10
ok done. Thank to me :>
I) -7s^2+28st+21su
II) -8c^2+20cd
((–7) + (3 + i)) - (2 - (6 + i)) =-9 + 9 i
False however a one to one function has to be represented by a straight line the way to test a function is the vertical line test
