Question

A função real de variável real, definida por f(x) = (3a - 6)x + 2, é crescente quando
Escolha uma:

a, a < 2
b. a > 0
O C. a > 2
O d. a = 2
e. a = 0

Answer 1

$\mathsf{f(x)=(3a-6)x+2}$

$\mathsf{3a-6>0}\\\mathsf{3a>6}\\\mathsf{a>\dfrac{6}{3}}\\\large\boxed{\boxed{\boxed{\boxed{\mathsf{a>2}}}}}$

$\huge\boxed{\boxed{\boxed{\boxed{\mathsf{\maltese~~Alternativa~~c}}}}}$
