Answer:
A
Step-by-step explanation:
f(x) = 7x² - 15x + 2
A) f(1) = 7*1² - 15*1 +2 = - 6
f(1.5) = 7*(1.5)² -15*1.5 + 2 = - 4.75
B) f(2.2) = 7*(2.2)²-15*(2.2)+2 = 2.28
C) f(1) = 7*1² - 15*1 +2 = - 6
f(1) = 7*2² - 15*2 +2 = 0
D) not for all real numbers because we already have
f(2.2) = 7*(2.2)²-15*(2.2)+2 = 2.28 that is positive.
it would be the third answer choice, when doing this you always make sure that there is multiplication or division you do those first going left to right, even if there is addition first, you still would do either multiplication or division first.
