Answer:

$x = 4$

$x = - 7$

Step-by-step explanation:

$x^2+3x-28 \\ x ^{2} + 7x - 4x - 28 \\ x(x + 7) - 4(x + 7) \\ (x - 4)(x + 7) \\ x - 4 = 0 \: \: \: or \: \: \: x + 7 = 0 \\ x = 4 \: \: \: \: \: \: \: \: \: \: or \: \: \: \: x = - 7$

Answer:

f(x) = 3x

Step-by-step explanation:

The equation of a line passing through the origin is

y = mx ( m is the slope )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 3)

m = $\frac{3-0}{1-0}$ = 3 , then

y = 3x ← is the equation of the graphed line
